You are in a hurry on an interstate with three lanes in your direction. Traffic is moderate, and some cars around you change lanes often. Which plan is safest and follows Oklahoma law?
Correct answer: Stay in one lane that fits your speed and change lanes only when needed
Why
Each lane change puts you near another driver's blind spot and forces others to react, so frequent weaving raises the risk of a crash and saves little time. Pick a lane that suits your speed, stay near the middle of it, and change lanes only for a reason, such as to pass or to reach an exit. On an interstate or turnpike, Oklahoma law allows travel in the left lane only to pass, or when traffic or merging makes it necessary. Do not ride alongside other cars; stay out of their blind spots.
