A bus driver should choose a safe driving speed, primarily based on
- the schedule.
- the road conditions. ✓
- the number of passengers.
- the condition of the brakes.
Answer: B. the road conditions.
A bus driver should choose a safe driving speed primarily based on the road conditions.
Why this is the answer
The handbook tells heavy-vehicle drivers to pick a safe speed that is not too fast for the vehicle's weight and length, the grade, the weather, and the road conditions. It also says travelling speed depends on driving conditions, including traffic flow, while staying within the speed limit. That makes road conditions the stated basis for choosing a safe speed, rather than the timetable or passenger count.
Why the other answers are wrong
- A. the schedule. — The schedule is not given as a factor for choosing a safe speed; the handbook bases speed on driving conditions.
- C. the number of passengers. — The number of passengers is not mentioned as the basis for a safe speed; the passages point to road and driving conditions instead.
- D. the condition of the brakes. — The condition of the brakes is not the stated basis for choosing speed; the handbook points to road conditions and other driving factors.
Remember it
Think of your speed as a response to the road in front of you, not to the clock.
