Many driving-test errors begin before the vehicle moves sideways: the driver fails to plan, signal, check mirrors, check the blind spot, or select the correct lane.
Visual guide for this module
Study the shape, color, signal, or marking and name the safe response before reading the explanation.
Plan a turn before the corner
Observe signs and markings, select the appropriate lane early, signal, reduce speed smoothly, scan for pedestrians and bicycles, and complete the turn into the lawful lane while maintaining control.
Lane changes need multiple checks
Use mirrors to understand surrounding traffic, signal your intention, check the blind spot over your shoulder, and move only when adequate space exists. Do not assume another driver will create space for you.
Passing requires sight distance and legality
Before passing, determine whether the maneuver is permitted and whether you can see enough roadway to complete it safely. Never let impatience replace a clear safety margin.
Bicycle lanes require special attention
Look carefully for bicyclists before crossing or entering a bicycle lane where permitted. A turn that appears clear in the mirror may still conflict with a rider in a blind spot.
Quick self-check
- Can I describe the complete lane-change sequence?
- Do I know why the blind-spot check cannot be replaced by mirrors alone?
- Can I explain what I should look for before turning across a bicycle lane?
