What to Do When Your Car Breaks Down on a Highway

Step-by-step: what to do when your car breaks down on a highway. Safety first, diagnostic call, assistance, no destroyed engine.

A highway breakdown is almost never as bad as it feels in the first two minutes. Most cases are a flat tyre, an overheated radiator, or a dead battery — none of them require a towing disaster if you follow a calm sequence.

Step 1: Safety — do this first

  1. Indicate left immediately. Move to the shoulder or the safest off-road point you can reach — do not stop in a live lane.
  2. Switch on all hazard lights the moment you start slowing.
  3. If at night, use interior lights too.
  4. Everyone out of the car, on the non-traffic side, behind the guard rail if possible. Do not stand next to the vehicle.
  5. Place a warning triangle 15–30 metres behind the car. Every toolkit has one.

The highway death risk is the traffic, not the broken car. Until step 1 is done, do nothing else.

Step 2: Quick diagnostic — should I drive?

Some problems are "wait for help". Some are "do not drive another metre". The difference matters.

  • Flat tyre: safe to change on the shoulder. Do not drive far on a flat — it destroys the rim.
  • Battery / won't start: safe to wait. Jump-start and carry on.
  • Overheating (steam from bonnet): turn off immediately. Do not restart. Driving an overheated engine another 500 metres can crack the head.
  • Oil warning light: stop. Do not drive. You have minutes before the engine seizes.
  • Brake failure / no brake: stop immediately via downshift and handbrake. Do not drive further.
  • Strange noise only: call a mechanic before deciding. A 5-minute call with a mechanic on TrunkCall can tell you whether to drive slowly to the next exit or wait for tow.

Step 3: Call for help — the right sequence

  1. Call your car manufacturer's 24-hour roadside assistance. Most cars under 5 years old have free RSA — check the owner manual or call the dealer.
  2. Call your insurer's RSA if you have it as an add-on.
  3. Call highway emergency: 1033 works on most national highways for medical, police, and mechanical help.
  4. Call a local mechanic on TrunkCall for remote diagnosis — this can save you a Rs 5,000 tow if it turns out to be something simple.

Step 4: While waiting

  • Stay outside the car if it is safe (guard rail, shoulder).
  • Do not accept help from strangers who 'just happen to pass' — there are predatory tow-gangs on some highways.
  • Take photos of the vehicle position and any damage for insurance.
  • Drink water if it is hot. Share your location with a family member.

Step 5: When the mechanic or tow arrives

  • For tow: insist on a flatbed for all-wheel-drive cars and most luxury cars. Flat-towing can damage the transmission.
  • For on-spot repair: ask for a written estimate before authorising work. Highway mechanics over-charge when they sense panic.
  • Keep your car documents and wallet with you. Do not leave valuables in the car during tow.

Frequently asked

Does my car insurance cover a tow?

Most comprehensive policies include roadside assistance or offer it as a cheap add-on (Rs 500/year). Check your policy.

Should I call the police?

Only if there was an accident or if you are being harassed. Otherwise, highway emergency 1033 or RSA is faster.

How long will RSA take?

Typical arrival on major highways is 45–90 minutes, longer in remote stretches. Some manufacturers guarantee under 60 minutes.

Is it safe to sleep in the car if it is late at night?

Only in well-lit service areas. On open highway shoulders, stay alert and outside the vehicle where possible.
