What you need to understand
Signals give other road users time to understand your intended movement. Stopping distance is equally time-dependent because a vehicle travels while the driver perceives, reacts and finally brakes.
Key points to remember
- Signal when leaving the curb, turning or changing lanes.
- Perception and reaction occur before braking.
- Road, vehicle and driver condition affect the final distance.

Practice questions
1. Which manoeuvre requires a signal?
- Moving away from the curb
- Continuing straight in the same lane
- Reducing radio volume
- Checking the rear-view mirror
Show answer and explanation
Correct answer: Moving away from the curb
The guide requires signals when moving away from the curb or parking lane, turning left or right, and changing lanes.
2. Which combination makes up total stopping distance?
- Perception distance plus reaction distance plus braking distance
- Vehicle length plus lane width
- Mirror distance plus signal distance
- Acceleration distance plus parking distance
Show answer and explanation
Correct answer: Perception distance plus reaction distance plus braking distance
Total stopping distance combines how far the vehicle travels while the driver perceives the hazard, reacts, and then brakes.
Exam-day strategy
Look for answers that include the human-response stages as well as mechanical braking.
Read every word, especially qualifiers such as must, only, before, and NOT. Eliminate choices that contradict the official rule, then select the safest complete answer.
