How should drivers react to a slow-moving work vehicle blocking a traffic lane?

The appropriate reaction for drivers when encountering a slow-moving work vehicle blocking a traffic lane is to pass in the direction indicated by the arrows. This option prioritizes safety and adherence to traffic instructions that are likely in place to guide vehicles around roadwork or maintenance activities.

When work vehicles are operating on public roads, they often employ signage, cones, and arrows to direct traffic safely. Following the arrows allows drivers to navigate past the obstruction in a manner that is safe for both themselves and the workers. This practice not only facilitates smooth traffic flow but also reduces the risk of accidents that could occur from abrupt lane changes or unexpected stops.

The other options may lead to confusion or unsafe driving behavior. For instance, following closely behind a work vehicle could create a dangerous situation, as the driver may not be able to react quickly enough to sudden stops or other changes in the vehicle's speed. Stopping and waiting for instructions might cause unnecessary delays and could hinder the overall traffic flow, while turning around to find another route, while sometimes necessary, may not be practical in all situations and could contribute to congestion elsewhere. Therefore, passing as directed by arrows is the safest and most efficient option.
