About Hill start: two risks, one coordinated action: which statements are correct? (multiple answers possible)
This requires a well-coordinated use of the handbrake, the throttle, AND the clutch pedal — none of the three is secondary.
In this sentence 'afslaat' stands alongside 'rolling backward' as the car's second risk, not your steering direction: the engine stalls.
The only real risk during a hill start is the car rolling back; a stalling engine is not dangerous, just annoying at most.
When pulling away on a hill you only use the throttle and clutch; the handbrake is only meant for when you park the car.
Explanation
Book p.158 - pulling away on a hill requires well-coordinated use of the handbrake, the throttle and the clutch pedal, to prevent the car from rolling back or stalling — trap: handbrake seen only as a parking aid.
