A driver operating a loaded commercial vehicle is stopped at a stop sign on an access road, preparing to turn right into a two-lane roadway with traffic traveling at . When assessing traffic gaps to enter the flow safely, which principle must guide the driver's decision?
- AThe driver only needs a gap equal to the vehicle's total stopping distance, as approaching traffic has the legal obligation to yield to merging trucks.
- The driver must select a gap large enough to enter the roadway and accelerate up to the speed of traffic without forcing oncoming vehicles to brake or swerve.Cevap
- CThe driver should utilize standard passenger car gap intervals, relying on the following-distance space cushions of oncoming drivers to absorb entry delays.
- DThe driver only needs clearance to bring the front cab across the shoulder line, as rear off-tracking will automatically keep the vehicle clear of the oncoming lane.
Cevap
The driver must select a gap large enough to enter the roadway and accelerate up to the speed of traffic without forcing oncoming vehicles to brake or swerve.
Because large and loaded commercial vehicles accelerate slowly, safe traffic entry requires a gap large enough to pull onto the road and accelerate up to the prevailing traffic speed without impeding oncoming vehicles.
Adım Adım Çözüm
Anahtar Kavram
Entering and crossing traffic safely requires large gaps that account for heavy vehicle acceleration limitations and vehicle length.
