Study Notes

Safety Features and Driving Techniques

Safety features cannot change the laws of physics; they do not enhance vehicle performance or improve driver reaction time.
Safety devices help drivers regain control of their vehicles when they misjudge a situation, but only if drivers understand how to use them correctly.
To avoid skids, maintain a safe margin and avoid driving at the limits of tire adhesion.
Driving on slippery surfaces requires a reduced speed and increased braking distance.
Road surface, weather, and driver error can all contribute to skids.
Skids are caused by excessive speed, harsh steering, aggressive acceleration, or sudden braking.
When driving on slippery surfaces, smooth braking, steering, and gear changes are essential to maintain control.
On slippery roads, it is essential to observe road conditions, anticipate hazards, and plan strategies accordingly.
Check tire pressure and condition regularly to ensure optimal grip.
Inspect vehicle brakes before driving, particularly on slippery surfaces.
Understeer occurs when a vehicle turns less than intended, whereas oversteer happens when a vehicle turns more sharply than intended.
The tendency for understeer or oversteer is present even at low speeds.
Driving safely and avoiding skids is preferable to attempting to recover from a skid.

Avoiding Skids

Aim to control your vehicle to prevent skids by driving cautiously and anticipating potential hazards.
Reduce speed in slippery conditions to increase grip.
Use lower revolutions per minute (rpm) to avoid wheelspin, especially when accelerating from a standstill.
Ensure smooth steering and smooth gear changes to maintain control.
Employ the principles of cornering while driving on slippery surfaces, adjusting speed as needed.

Recognizing Skid Causes

Anti-lock braking systems (ABS) cannot increase tire grip or fully prevent skids, but they can help drivers maintain steering control while braking.
When ABS engages, the brake pedal will pulsate, and a warning light will appear on the dashboard.
Emergency brake assist (EBA) boosts braking pressure in emergency situations, preventing wheels from locking up.

Understanding Traction Control Systems

When a vehicle accelerates, the power transmitted to the driving wheels can exceed available grip, leading to wheelspin.
Wheelspin reduces acceleration and stability, especially on slippery surfaces.
Traction control systems help to prevent wheelspin by modulating engine power and applying brakes to individual wheels.
