The Importance of Preventive Maintenance
A driver's responsibility extends beyond simply operating a vehicle; it includes ensuring the vehicle is in a safe, roadworthy condition. Preventive maintenance is essential to avoid accidents caused by mechanical failure. By regularly checking key components, you can identify and rectify potential issues before they become dangerous, ensuring your safety and the safety of others on the road.
Tyres: Your Connection to the Road
Tyres are the single most critical component requiring frequent supervision by the driver. They are your vehicle's only point of contact with the road surface, and their condition directly impacts braking, steering, and overall stability.
Tyre Pressure
Maintaining correct tyre pressure is vital for safety and performance. You should check the pressure frequently, and always before starting a long journey.
- When to Check: Always check tyre pressure when the tyres are cold to get an accurate reading. Driving heats the air inside, which increases pressure and can give a false reading.
- Consequences of Incorrect Pressure: Incorrect pressure leads to uneven tyre wear and significantly increases the risk of a dangerous blowout. Underinflated tyres, for example, show excessive wear on their outer edges.
Tyre Condition and Performance
- Regular Inspections: Regular visual checks allow you to spot deterioration, cuts, or bulges early, helping to prevent blowouts.
- Environmental Factors: Heat accelerates tyre wear, so high temperatures can shorten a tyre's lifespan. Wet roads dramatically reduce tyre grip, making it essential to slow down and at least double your normal safety distance.
- Vehicle Load: Exceeding the vehicle's maximum authorised load impairs tyre performance, affects handling, and compromises safety.
Spare Tyres
In case of a flat tyre, you may need to use a spare. It's important to understand their limitations.
- Temporary-Use Spares: These are often smaller and lighter than standard tyres. When using one, you must always follow the manufacturer's instructions. Critically, you should never exceed 80 km/h and should limit the distance travelled, replacing it with a standard tyre as soon as possible.
- Trailers: While a spare wheel for a trailer is not compulsory, other safety equipment is.
Braking System
A fully functional braking system is non-negotiable for safe driving.
- Primary and Secondary Brakes: The foot brake (service brake) is the primary system and acts on all four wheels. The handbrake (parking brake) is a secondary system that typically acts only on the rear wheels.
- Brake Failure: If your foot brake fails while driving, remain calm. Immediately begin to downshift through the gears to use the engine to slow the vehicle. At the same time, apply the handbrake progressively and carefully to bring the vehicle to a stop.
- Long Descents: On long, steep descents, relying solely on your brakes can cause them to overheat and fail (a condition known as brake fade). To prevent this, shift to a lower gear and use engine braking to control your speed.
Engine and Vehicle Systems
Fluid Checks
- Engine Oil: To get an accurate reading, check the engine oil level when the vehicle is on level ground and the engine is stopped and cold.
- Battery: If your vehicle has a serviceable battery, top it up only with distilled water. Never use tap water or acid, as they can damage the battery's internal components.
Other Key Systems
- Exhaust: A key indicator of a damaged exhaust pipe is that the engine will sound noticeably louder than normal.
- Suspension: Worn shock absorbers can cause the vehicle to bounce excessively. This can lead to the headlights oscillating, which can dazzle oncoming drivers at night.
- Air Conditioning: Using the air conditioning system places an additional load on the engine, which in turn increases fuel consumption.
Fuel Efficiency
Your driving style has a direct impact on your vehicle's fuel consumption and emissions. This is particularly true for motorcycles, where smooth, efficient riding can significantly reduce both. Avoiding harsh acceleration and braking contributes to better fuel economy for all vehicles.
Required Safety Equipment
The law requires certain vehicles to carry specific safety equipment. It is your responsibility to know and comply with these rules.
Fire Extinguishers
The requirement to carry a fire extinguisher depends on the vehicle type:
- Not Compulsory: Private passenger cars and motorcycles are not required to carry a fire extinguisher.
- Compulsory: Trucks with a Maximum Authorised Mass (MAM) over 3,500 kg must always carry an approved fire extinguisher. Passenger cars that are towing a trailer must also carry one. A fire extinguisher is also compulsory for the trailer itself.
Reflective Vests
High-visibility reflective vests are crucial for safety if you have to exit your vehicle on a busy road.
- Requirement: Truck drivers must carry an approved reflective vest inside the vehicle.
- Approval: Any reflective vest carried in a vehicle must be type-approved to ensure it meets the required safety standards for visibility.
