Brakes, Lights & Signals Check

Learning objectives

After completing this lesson learners should be able to:

• Explain why brakes, lights and signals are critical safety systems
• Perform a simple visual and functional pre-drive check
• Recognise warning signs of possible brake problems
• Check headlights, brake lights, indicators and hazard lights
• Understand why visibility matters especially at night and in poor weather
• Recognise when a warning light or unusual vehicle behaviour requires professional attention
• Understand why a vehicle should not be driven when a critical safety system is clearly defective

Your vehicle needs to stop and communicate

Safe driving depends on more than the driver's decisions. The vehicle must also be capable of stopping when required, showing other road users when it is slowing or stopping, indicating a change of direction, helping the driver see the road, and making the vehicle visible to others. Indian road-safety guidance specifically recommends regularly checking brakes, tyres, lights and signals to keep a vehicle roadworthy.

A quick brake check

Before starting a journey, pay attention to how the brake pedal feels. A healthy braking system should give you a predictable and controlled response. Be alert to a brake pedal that feels unusually soft or spongy, excessive pedal travel, the vehicle pulling to one side while braking, grinding or unusual noises, vibration during braking, a brake warning light, or a noticeable change from the vehicle's normal braking behaviour. These signs should not be ignored. Do not attempt to diagnose or repair a braking system yourself unless you are properly qualified. If braking behaviour changes significantly, have the vehicle inspected by a qualified professional.

Brake fluid and leaks

Brake systems require appropriate hydraulic or mechanical components to function correctly. For vehicles using hydraulic brakes, look for obvious signs of fluid leakage around the vehicle and pay attention to any warning indicators. Do not treat a brake-fluid warning or suspected leak as a routine maintenance reminder — a braking-system problem can become a serious safety issue. If the vehicle's braking system shows a warning or behaves abnormally, stop in a safe location when possible and seek appropriate professional assistance.

Check your lights

A simple light check can identify problems before you enter traffic. Check that the appropriate lights are functioning: headlights, high beam, low beam, rear lights, brake lights, turn indicators, hazard warning lights and number-plate illumination where applicable. Government vehicle-fitness guidance specifically lists stop lights, direction indicators and other necessary lights as systems that should be in good working condition. It also identifies proper headlight fitment and functioning dip/high-beam operation as important checks.

Brake lights are a message

Brake lights are not there for you — they communicate with the driver behind you. When you slow or stop, the driver behind needs enough information to react. A failed brake light removes part of that communication. A simple way to check them is to have another person observe the rear of the vehicle while you operate the brake, or use a safe reflective surface where practical. Never perform a vehicle check in a way that puts you or another person in traffic.

Indicators communicate intention

Indicators tell other road users what you intend to do. They are particularly important before turning, changing lanes, moving around obstacles, and entering or leaving a road position. Indian Central Motor Vehicle Rules specify requirements for direction indicators and stop lamps on applicable motor vehicles, including visibility and operation requirements. But having a functioning indicator is only half the job — the driver must also use it appropriately and early enough to communicate the intended manoeuvre.

Lights help you see and be seen

Headlights have two jobs. They help illuminate the road ahead when visibility is reduced, and they help other road users recognise your vehicle. Keep lenses clean and check for broken lenses, moisture or water entry, dim or failed bulbs, incorrect beam operation and damaged housings. Government vehicle-fitness guidance specifically identifies water entry in headlamps and non-functioning headlights as issues requiring attention.

The dashboard can warn you

Modern vehicles can tell you when something needs attention. Pay attention to warning lights relating to the braking system, ABS, the electrical system, lighting, and the engine or other critical systems. Do not assume that every warning light can be ignored until the next service. If a red or critical safety warning appears, consult the vehicle manufacturer's instructions and seek professional assistance as appropriate. MoRTH's vehicle inspection requirements include checks for warning lights associated with ABS, brake systems and other vehicle systems.

The 60-second pre-drive check

Before moving the vehicle, develop a simple routine. 1. Walk around — look for obvious damage, leaks or anything unusual. 2. Brakes — pay attention to pedal feel and any unusual noise or behaviour. 3. Lights — check headlights, rear lights and brake lights. 4. Indicators — check left, right and hazard indicators. 5. Dashboard — look for warning lights that should not remain illuminated. 6. Windscreen — make sure your view is clear. 7. Mirrors — ensure mirrors are clean, secure and correctly adjusted. This does not replace scheduled servicing or professional inspection; it is a simple final check before entering traffic.

Know when not to drive

One of the most important vehicle-safety decisions is knowing when a vehicle should not be driven. Do not ignore serious warning signs such as major brake problems, a brake warning that indicates a fault, headlights that are not functioning when they are needed, brake lights that are not functioning, severe steering or braking abnormalities, significant fluid leakage, or any condition that makes the vehicle unsafe to control. Find a safe location, arrange appropriate assistance and have the vehicle inspected. The goal is not to become a mechanic — the goal is to recognise when your vehicle is telling you that something is wrong.
