Question 5509
On this one-way road, how much lateral clearance must the truck leave when passing this bicycle?
- A distance proportional to the speed and the type of roadway.
- At least 1.5 meters in all cases.
- At least 1.5 meters and a complete lane change, because the roadway has more than one lane per direction.
Show answer and explanation
Correct answer: At least 1.5 meters and a complete lane change, because the roadway has more than one lane per direction.
In the image, the roadway has more than one lane in the truck's direction, so the truck must move completely into the other lane to pass the bicycle, as well as leave at least 1.5 meters of clearance. With only one lane in each direction, you would leave that 1.5 meters by using as much of the oncoming lane as necessary. The minimum is fixed and does not depend on speed.
