An overheating engine can quickly turn a cooling-system problem into major engine damage. Learn how to recognize the warning signs, when to pull over, why you should never open a hot cooling system, and when your vehicle should be towed instead of driven.
Your vehicle has broken down.
You've managed to get it onto the shoulder.
The hazard lights are flashing.
Roadside assistance is on the way.
Now comes a question many drivers don't think about:
Where should you wait?
Standing beside your vehicle may feel natural.
After all, that's where your belongings are, and you may want to watch for the tow truck.
But a disabled vehicle sitting beside moving traffic can still be struck.
And if you're standing:
Beside it.
Directly in front of it.
or:
Directly behind it.
you may be placing yourself in a dangerous position.
There isn't one perfect waiting location for every roadside breakdown.
Road design, traffic direction, visibility, terrain, weather, and the condition of your vehicle all matter.
The goal is simple:
Create as much reasonable separation as possible between yourself and moving traffic without moving into another hazard.
Here's what you should consider.
Before deciding where to wait, take a moment to look around.
Ask:
Where is traffic coming from?
How fast is it moving?
How wide is the shoulder?
Can approaching drivers see my vehicle?
Is there a guardrail?
Am I near a curve or hill?
Am I on a bridge?
Is there another roadway nearby?
Is there somewhere genuinely safer that I can reach without crossing traffic?
Don't choose a waiting location simply because it is convenient.
Choose it based on:
Risk.
You don't always need to get out of the vehicle.
If your vehicle is well away from active traffic, there is no fire, smoke, fuel leak, or other immediate danger, and exiting would expose you to traffic, remaining inside with your seat belt fastened may sometimes be the safer option.
However, the situation changes if the vehicle is:
Smoking
On fire
Leaking fuel
In an active traffic lane
In an extremely vulnerable position
Exposed to another immediate hazard
There is no universal rule that says:
“Always stay inside.”
And there is no universal rule that says:
“Always get out.”
Assess the actual conditions around you.
A highway shoulder can be narrow.
Traffic may be passing only a few feet away.
Before opening a door:
Look.
Whenever reasonably possible, exit from the side farther away from moving traffic.
That may mean climbing across the vehicle and using a passenger-side door instead of opening the driver's door directly toward passing vehicles.
Make sure children and passengers understand what you're doing before anyone exits.
Traffic direction should influence where you position yourself.
Look at:
Where approaching vehicles are coming from.
Where they would travel if someone drifted onto the shoulder.
Where your disabled vehicle could move if struck.
Do not position yourself somewhere simply because it appears to be away from the lane.
Think about:
What could happen if another vehicle hits yours?
The shoulder may look like a safe parking area.
It isn't necessarily one.
Drivers can:
Drift out of their lane
Become distracted
Misjudge the shoulder
Lose control
Be affected by weather
Swerve to avoid something
Fail to notice a stopped vehicle
If you're standing directly beside your disabled vehicle when another vehicle strikes it:
You may have very little room to escape.
Avoid spending unnecessary time on the traffic-facing side of the vehicle.
Standing directly behind your disabled vehicle can also put you in a dangerous position.
If another vehicle leaves the travel lane and strikes your car from behind, the disabled vehicle can be pushed forward.
You may also be directly in the path of the approaching vehicle.
Do not treat the rear of your car as a protected waiting area.
This is especially important on high-speed roads.
The front isn't automatically safe.
If your disabled vehicle is struck from behind, it may be pushed forward.
That means anyone standing directly in front of it could potentially be placed in danger.
Think beyond:
“Where will traffic hit?”
Also consider:
“Where could my vehicle move if it gets hit?”
If conditions allow you to safely exit and reach an area separated from traffic, creating distance can reduce your exposure.
The best available location may vary.
You might have:
Wide grassy area
Protected roadside area
Guardrail
Parking area
Embankment
Nearby safe location
But inspect the area before moving toward it.
Away from traffic does not automatically mean:
Safe.
Not necessarily.
A guardrail may provide useful separation from traffic in some roadside situations.
But before moving behind one, look carefully.
There could be:
Steep drop
Drainage ditch
Water
Rocks
Construction
Dense vegetation
Uneven terrain
Another roadway
Other hazards
Do not climb over a guardrail without knowing what's on the other side.
If there is a safe, accessible area behind the barrier that provides additional separation from traffic, it may be preferable to standing immediately beside the vehicle.
But evaluate the actual environment.
This can create a dangerous pinch point.
Imagine:
Guardrail → You → Disabled Vehicle → Traffic
If another vehicle strikes your car and pushes it toward the guardrail:
You may have nowhere to go.
Avoid positioning yourself in narrow spaces where the vehicle could trap you against:
Guardrail
Wall
Barrier
Another vehicle
Fixed object
Always think about possible vehicle movement.
A wide shoulder gives you more separation from traffic.
That's good.
But don't become overly comfortable simply because the shoulder is several feet wide.
Highway traffic may still be traveling at:
55, 65, 70 mph or more.
A distracted driver can cross that distance quickly.
Use the extra space to increase separation from moving traffic.
Don't use it as an invitation to stand beside the car unnecessarily.
A narrow shoulder can leave very little separation between your vehicle and passing traffic.
If your mirror is only a few feet from moving vehicles:
Treat the location as hazardous.
Do not attempt repairs on the traffic-facing side simply because the repair seems easy.
This includes:
Changing a tire
Looking underneath the vehicle
Inspecting body damage
Checking a wheel
Trying to diagnose a noise
Call roadside assistance when the location makes roadside work unsafe.
Breaking down near a curve can reduce the amount of time approaching drivers have to see you.
A driver may come around the bend and suddenly encounter:
Your stopped vehicle.
If your vehicle can still be moved safely to a more visible location, that may reduce risk.
If it cannot:
Keep hazard lights operating when appropriate.
Avoid standing near the travel lane.
Do not walk around the curve into traffic trying to warn drivers yourself.
If the vehicle creates an immediate roadway hazard:
Contact emergency services or the appropriate highway authority.
The crest of a hill can hide your vehicle from approaching traffic.
Drivers may not see a disabled vehicle until they reach the top.
Likewise, a vehicle stopped immediately beyond the crest may be difficult to see.
Consider:
Can approaching traffic see me in time?
If the vehicle is in a dangerous location and cannot be moved:
Call for appropriate assistance.
Do not put yourself in the roadway trying to direct traffic.
A breakdown on a bridge can be particularly challenging.
You may have:
Narrow shoulder
Concrete barriers
No grassy area
Limited escape routes
High-speed traffic
Drop-offs
Water below
Do not climb over a bridge barrier looking for somewhere to wait.
And do not stand in a narrow gap between:
Your vehicle and the barrier.
If the vehicle is creating an immediate traffic hazard or you cannot reach a reasonably safe position:
Contact emergency services or the appropriate roadway authority.
Tell them clearly:
“My vehicle is disabled on a bridge.”
If your vehicle breaks down, walking down the shoulder may expose you to traffic for an extended period.
Unless remaining near the vehicle creates a greater immediate danger, don't assume walking half a mile toward an exit is automatically safer.
You may encounter:
Narrow shoulder
Bridge
Curve
Construction
Entrance ramp
Reduced visibility
Other hazards
Roadside assistance can come to you.
Not every breakdown happens on an interstate.
If your vehicle becomes disabled near an intersection, traffic may approach from:
Multiple directions.
Drivers may be:
Turning
Accelerating
Braking
Changing lanes
Watching traffic signals instead of your vehicle
Do not stand in the roadway directing traffic unless you are an authorized responder.
If possible, move the vehicle completely away from the intersection.
Once stopped, choose a waiting location away from the paths vehicles are likely to travel.
Ramps can be deceptive.
Drivers may:
Accelerate rapidly
Decelerate suddenly
Change lanes
Look over their shoulder
Focus on merging traffic
A shoulder beside a merge area may expose you to vehicles that are changing direction.
If your vehicle is stopped near a ramp:
Pay attention to traffic patterns, not just the painted lane lines.
Construction areas may have:
Narrow lanes
Temporary barriers
Reduced shoulders
Changing traffic patterns
Workers
Heavy equipment
Limited places to stop
If you break down in a construction zone and cannot reach a safe stopping location:
Contact the appropriate roadside or emergency service.
Do not climb barriers or enter active construction areas unless directed by authorized personnel.
Rain, snow, ice, fog, and darkness can make roadside waiting more dangerous.
Drivers may have:
Less visibility.
Less traction.
Longer stopping distances.
A location that feels reasonably safe on a clear afternoon may be much more dangerous during heavy rain at night.
Keep this in mind when deciding whether to:
Stay inside
or:
Exit and move farther away.
During snow or icy conditions, think about where an out-of-control vehicle might go.
Road shoulders, medians, and areas immediately beyond curves can become paths for vehicles that lose traction.
Distance and barriers may help, but always evaluate the actual terrain.
At night:
Your vehicle may be harder to see.
You may also have difficulty seeing:
Ditches
Drop-offs
Uneven ground
Barriers
Traffic approaching from behind
Use a flashlight when appropriate.
But avoid standing near traffic simply to make yourself visible.
Your disabled vehicle's hazard lights and appropriate roadside warning equipment may help drivers see the situation.
Your body should not become the warning device.
Reflective warning equipment can improve visibility in some situations.
However:
Do not walk into or alongside dangerous high-speed traffic just to place it.
If deploying warning equipment would require you to expose yourself to moving vehicles:
Don't do it.
Personal safety takes priority.
You may feel that approaching drivers aren't seeing your vehicle.
Do not step into the roadway and attempt to wave them around.
You're placing yourself directly in the hazard you're trying to prevent.
If your disabled vehicle is blocking traffic:
Contact emergency services or the appropriate roadway authority.
Let trained responders manage traffic.
Children should never be allowed to:
Wander around the shoulder
Stand behind the vehicle
Play near a guardrail
Walk toward traffic
Move between stopped vehicles
If remaining inside the vehicle is the safest available option, keep children properly restrained where appropriate.
If you must exit, move the entire group together to the safest accessible location.
A roadside breakdown can frighten animals.
A dog that normally follows commands may panic around:
Loud trucks
Horns
Wind
Strange surroundings
Keep pets secured.
Do not allow them to roam along the shoulder.
When roadside assistance arrives, give the professional room to work.
Do not gather around:
Tow truck
Flat tire
Engine compartment
Traffic-facing side of vehicle
The roadside professional may need to position equipment or move the vehicle.
Follow their safety instructions.
When the tow provider arrives, the vehicle may need to be:
Winched
Loaded
Repositioned
Lifted
Secured
Do not stand:
Behind the disabled vehicle.
Between the vehicle and tow truck.
Near towing cables or equipment.
In the traffic-facing work area.
Let the operator manage the recovery.
If your vehicle is disabled in an active traffic lane:
This is a different level of roadside danger.
Turn on your hazard lights.
Avoid getting out into moving traffic unless remaining inside presents a more immediate danger.
Contact emergency services or the appropriate highway authority.
Tell them:
Road
Direction
Nearest exit or mile marker
Lane you're blocking
Vehicle description
For example:
“My vehicle is disabled in the right travel lane on I-40 West near Exit 44.”
That information matters.
Traffic isn't the only hazard.
If the vehicle has:
Fire
Heavy smoke
Strong fuel odor
Visible fuel leak
you may need to create significantly more distance from the vehicle.
Contact emergency services when appropriate.
Do not remain inside a vehicle simply because you're afraid of roadside traffic if the vehicle itself presents an immediate danger.
This is why every roadside situation must be evaluated individually.
Ask yourself five questions:

Identify the direction and proximity of moving vehicles.
Consider what could happen if another driver leaves the roadway.
Think about where your disabled vehicle could move if struck.
Look for:
Fire • Fuel • Drop-offs • Water • Barriers • Construction • Weather
Choose the safest accessible location based on the complete situation.
Whenever reasonably possible, avoid:
🛑 Standing on the traffic-facing side of the vehicle
🛑 Standing directly behind the vehicle
🛑 Standing directly in front of the vehicle
🛑 Standing between the vehicle and a guardrail or wall
🛑 Standing in an active travel lane
🛑 Standing around a blind curve
🛑 Standing where approaching drivers cannot see you
🛑 Standing near towing or recovery equipment
🛑 Walking unnecessarily along a high-speed roadway
🛑 Crossing highway lanes to reach another location
After getting the vehicle stopped:
✓ Turn on hazard lights
✓ Look at the direction of traffic
✓ Assess the width of the shoulder
✓ Check whether approaching drivers can see the vehicle
✓ Consider curves and hills
✓ Look for guardrails and barriers
✓ Check for drop-offs or other hazards
✓ Decide whether staying inside or exiting is safer
✓ Exit away from traffic when reasonably possible
✓ Keep children and pets secure
✓ Create distance from traffic when a safe area is accessible
✓ Avoid standing directly beside, behind, or in front of the vehicle
✓ Avoid getting trapped between the vehicle and a fixed object
✓ Call for assistance
✓ Reassess if conditions change
There isn't one roadside waiting location that is safest in every situation.
The answer depends on:
Traffic.
Vehicle position.
Road design.
Visibility.
Terrain.
Weather.
Other hazards.
Sometimes remaining seat-belted inside a vehicle that is well away from traffic may reduce your exposure.
Other times, getting out and moving to a safer accessible area may be the better decision.
What you generally want to avoid is unnecessarily positioning yourself:
Beside the disabled vehicle.
Directly behind it.
Directly in front of it.
or:
Between it and a fixed barrier.
Always think about what could happen if another vehicle leaves the roadway and strikes your car.
Don't just ask:
“Where can I stand?”
Ask:
“Where am I least exposed to moving traffic and other hazards?”
Because during a roadside breakdown:
Your vehicle is already disabled.
Don't allow where you wait to create another emergency.
Once you and your passengers are in the safest situation reasonably available, you can begin dealing with the vehicle.
FixFlowIQ can help you connect with vetted automotive professionals for your repair needs.
When submitting your repair request, include:
Year • Make • Model • Mileage
Describe what happened:
“Vehicle suddenly lost power on the highway.”
“Engine overheated and I pulled onto the shoulder.”
“Tire failed while driving.”
“Vehicle was towed after breaking down.”
Include useful:
Warning lights • Noises • Leaks • Photos • Videos
when they can be obtained safely.
