Skids occur when tyres lose grip on the road surface. Understanding the two main types of skid and how to correct them can prevent a loss of control from becoming a collision.
Understeer (Front-Wheel Skid)
Understeer occurs when the front wheels lose grip during cornering — the car continues straight instead of turning. This is common in front-wheel-drive vehicles when entering a corner too fast. Correction: release the accelerator gently (do not brake suddenly), and hold the steering in the intended direction. Do not turn the wheel further — this increases the skid. Wait for grip to return as speed reduces.
Oversteer (Rear-Wheel Skid)
Oversteer occurs when the rear wheels lose grip and swing outward — the car rotates around its front. Common in rear-wheel-drive vehicles and in any car on ice when braking. Correction: steer in the direction the rear is moving (counter-steer). If the rear swings right, turn the wheel right — this is called “catching” the skid. Release the accelerator but do not brake hard.
ABS and Skids
ABS prevents wheel lockup under braking but does not prevent all skids — particularly those caused by excessive cornering speed. Apply brakes firmly and straight, then steer once grip is restored.
Exam tip: The instinct to brake hard in a skid usually worsens it. The correct first action is almost always to gently release the accelerator.
