Driving safely over speed breakers and potholes

Speed breakers and potholes are part of almost every drive in India. Some speed breakers are painted and signposted; many are not. Potholes appear overnight in the monsoon and hide under water. Here is practical advice for cars and two-wheelers.

Slow down early

The most important habit is to lose speed before the hazard, not on it.

• Look further ahead than usual on unfamiliar roads. Vehicles in front braking or swerving suddenly are a clue.
• Ease off the accelerator and brake gently and in a straight line while you still have room.
• Check your mirrors before slowing, especially on highways where the vehicle behind may not expect it.

A gentle, early slowdown is kinder to your vehicle and much safer than a sudden stop that invites a rear-end collision.

Don't brake on the hazard itself

It feels natural to keep the brake pressed as you go over a speed breaker or through a pothole, but it makes things worse.

• In a car, braking pushes the nose down and compresses the front suspension. Hitting a bump with the suspension already compressed gives it less travel to absorb the impact, so the jolt to the tyres, rims and suspension is harsher.
• On a two-wheeler, braking on a bump or broken surface can lock or skid the wheel, especially the front.

Finish your braking before you reach the hazard, then release the brake and roll over it at a steady, low speed.

Go straight, not at an angle

Cross speed breakers and potholes with the wheels pointing straight. Crossing at an angle can unsettle the vehicle and, on a two-wheeler, make the front wheel slide sideways. On a bike, avoid leaning while crossing a bump.

Don't swerve at the last moment

A sudden swerve to dodge a pothole can put you in the path of another vehicle, a pedestrian or a rider. If there is space and time, change your line smoothly after checking mirrors. If not, it is usually safer to slow down and go through the pothole in a straight line than to swerve.

Keep your tyres right

Tyres are your first line of defence against potholes.

• Check pressure regularly, ideally when the tyres are cold, and inflate to the figure your vehicle maker recommends. You can usually find it in the owner's manual, on a sticker inside the door frame or near the fuel lid.
• Under-inflated tyres flex too much and are more easily pinched between the rim and the pothole edge, which can cut the tyre or bend the rim.
• Over-inflated tyres grip less and transmit more shock.
• Check for damage after a hard hit: bulges on the sidewall, cuts or a vibration in the steering. A sidewall bulge means the tyre should be inspected or replaced before a long drive.
• If the car starts pulling to one side after a pothole hit, get the wheel alignment checked.

Two-wheeler technique

Riders feel every pothole directly, so technique matters.

• Slow down and stay straight, as above.
• Rise slightly off the seat for larger speed breakers or rough patches if your bike and riding position allow it, keeping your knees and elbows slightly bent. Your legs then absorb the jolt instead of your spine.
• Keep a light but firm grip on the handlebar. A rigid grip transmits every shock to your arms and can make you oversteer.
• Look where you want to go, not at the pothole. Riders tend to steer towards whatever they stare at.
• Mind the pillion. Warn your passenger before a big bump so they can hold on.
• Wear a proper helmet, fastened, every time. It matters most precisely when a pothole catches you out.

Night driving

Potholes and unmarked speed breakers are much harder to see after dark.

• Drive slower than you would in daylight on roads you don't know well.
• Keep headlights clean and correctly aimed. Use high beam where it is safe and dip it for oncoming traffic.
• Watch the vehicle ahead. Its tail lights jumping or the brake lights coming on can warn you of a bump.

Rain and waterlogged potholes

The monsoon is the hardest time of year for potholes, because water hides them completely.

• Treat every puddle as a possible pothole. You cannot judge its depth from the surface.
• Slow right down before driving through water, and keep a steady, low speed rather than stopping in the middle.
• Stay in the tracks of the vehicle ahead where possible, since that path has just been driven over.
• Avoid deep water. If you can't see the road surface and there is no safe way round, wait or find another route. Water entering the engine air intake can cause serious damage.
• Test your brakes gently after driving through water, as wet brakes can be less effective at first.
• Leave more distance to the vehicle in front on wet roads.

Plan ahead

• Know your regular routes and where the bad stretches are.
• Leave a little extra time in the monsoon so you aren't tempted to rush.
• Use a navigation app that warns about hazards ahead, and report the ones you see so others are warned too. Report from a safe place, or ask a passenger to do it.
• Report persistent potholes to your local road authority so they get repaired.

How IndiaRoad Map can help

IndiaRoad Map, a free Android navigation app with ads, gives you a voice and on-screen warning about 10 seconds before a known pothole, speed breaker or stretch of bad road, never closer than 100 m. That is often enough time to slow down early, which is the most useful habit in this list. Hazards come from other drivers' phone sensors and manual reports, so the app can't know about every pothole, and it is no substitute for watching the road. Choosing a pothole warning app?
