What you need to understand
Roundabouts and lane changes require drivers to identify an available path before moving. Entering traffic yields to circulating traffic, and a lane change requires more than mirrors because blind spots remain.
Key points to remember
- Yield to traffic already circulating.
- Check mirrors and the relevant blind spot.
- Signals communicate intent but do not create priority.

Practice questions
1. What must a driver do before entering a roundabout?
- Enter first and then check for traffic
- Yield to traffic already circulating and enter when there is a safe gap
- Stop inside the roundabout to choose an exit
- Signal left and take any available lane
Show answer and explanation
Correct answer: Yield to traffic already circulating and enter when there is a safe gap
Traffic already in the circular roadway has priority. Enter only after yielding and finding a safe gap.
2. After checking both mirrors before a lane change, what additional observation is required?
- A quick shoulder check in the direction you plan to move
- A glance only at the speedometer
- A check of the passenger footwell
- No other check if the signal is on
Show answer and explanation
Correct answer: A quick shoulder check in the direction you plan to move
Mirrors do not show every area. A quick shoulder check reveals vehicles or cyclists in the blind spot before the lane change.
Exam-day strategy
Select the answer that checks, signals, yields and moves only when a safe gap exists.
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.
