How far?? Understanding stopping distances when driving

What are stopping distances?

A stopping distance is the total distance your car travels from spotting a hazard to a full stop. This distance consists of two main parts:

1. Thinking distance: This is the distance your car covers while you’re reacting to the need to stop, such as spotting a red light or another car pulling out.

2. Braking distance: This is the distance your car continues to move after you hit the brakes until it completely stops.

Both parts are influenced by factors such as your speed, car condition, and road surface.

How speed impacts stopping distances

Speed plays a major role in how long it takes to stop. The faster you drive, the longer it takes to come to a complete halt. Here’s a quick breakdown of approximate stopping distances on dry roads:

• 40 km/h: 26 metres

• 60 km/h: 45 metres

• 80 km/h: 69 metres

• 100 km/h: 98 metres

On wet roads, stopping distances increase significantly:

• 40 km/h: 30 metres

• 60 km/h: 54 metres

• 80 km/h: 85 metres

• 100 km/h: 122 metres

What affects your stopping distance?

Several factors can change how long it takes to stop your vehicle:

1. Vehicle weight and load: Heavier vehicles take longer to stop.

2. Vehicle age: Older cars might not stop as efficiently as newer models.

3. Brake condition: Worn brakes reduce stopping power, which is why regular brake checks and maintenance are crucial.

4. Tyre condition: Under-inflated or worn tyres require more braking pressure and can increase stopping distances.

5. Road conditions and weather: Wet or uneven roads make stopping more difficult.

6. Driver reaction time: Being alert is vital. On average, a driver takes about 1 second to react to an emergency.

Why efficient brakes are essential

Good brakes mean:

• Quick response: You can stop sooner, reducing accident risk.

• Safety in emergencies: Effective brakes can make the difference between a close call and a collision.

• Peace of mind: Reliable brakes give you confidence, especially in heavy traffic or challenging weather.

Tips for keeping your brakes in top shape

• Regular checks: Visit your mechanic regularly to inspect and if needed, replace your brake pads or rotors.

• Listen and feel: If you hear squealing, grinding, or feel vibrations when braking, get them checked out.

• Maintain brake fluid: Make sure your brake fluid is clean and topped up.

• Check your tyres: Ensure your tyres are properly inflated and have enough tread for optimal contact with the road.

What happens if brakes fail?

If your brakes are worn or fail, your stopping distance can increase significantly. In some cases, you might not be able to stop at all when you need to, which is why regular maintenance is so important.

No matter where you’re headed, understanding your stopping distances and maintaining your brakes and tyres are the key to safe driving. Stay alert, drive at safe speeds, and keep your car in peak condition for peace of mind on the road. Safe travels!
