If drivers do not adhere to right of way rules, which of the following may occur?

When drivers do not adhere to right of way rules, it often leads to an increase in accidents and collisions on the road. This rise in incidents can cause insurance companies to perceive a higher risk associated with insuring those drivers. As a result, drivers may see an increase in their insurance premiums to account for this elevated risk profile.

In contrast, the other options do not correlate with the consequences of disregarding right of way rules. Lower gas prices, more efficient travel times, and improved vehicle navigation have no direct connection to right of way adherence. Instead, these aspects focus more on market influences or technological advancements that do not stem from driver behavior regarding right of way. Therefore, adhering to right of way rules is crucial not only for safety but also for maintaining manageable costs in insurance.
