Question

Difficulty: MediumSpace to Cross or Enter Traffic

When turning right into a moving traffic stream from a stop sign, a commercial driver may proceed into a small gap under the expectation that approaching vehicles will slow down or change lanes to accommodate the truck.

Answer: Answer

Answer

False
Through traffic on a priority roadway maintains the right-of-way. Because heavy commercial vehicles accelerate slowly under load, the driver is responsible for waiting until there is a gap large enough to enter and reach traffic speed without causing oncoming vehicles to brake, slow down, or swerve.

Step-by-Step Solution

1
Identify the right-of-way rules governing vehicles entering a roadway from a stopped position.
Through traffic retains the legal right-of-way, and entering vehicles must yield until a safe gap is available.
Commercial motor vehicles must not impede the flow of traffic or create a hazard when entering travel lanes.
2
Analyze commercial vehicle acceleration characteristics and space requirements.
Because heavy commercial vehicles accelerate slowly, they require a substantially larger gap in traffic than passenger vehicles to reach cruising speed safely.
Entering into an inadequate gap forces through traffic to brake abruptly or swerve, increasing the risk of rear-end or sideswipe collisions.
3
Evaluate the safety principle regarding driver expectations of other traffic.
Defensive driving rules dictate that drivers must never rely on other road users to brake or yield when entering traffic.
Safe space management requires verifying that adequate space and time exist independently before executing the maneuver.
