California Driver License (DMV) Written Practice Test

When two vehicles enter the same lane at the same time, the general rule is to yield to the vehicle on your right. This ensures a smooth flow of traffic and helps prevent collisions. Therefore, B is the correct answer as the vehicle entering the lane from the right has the right-of-way. A is incorrect because being on the left does not automatically give a vehicle the right-of-way. Similarly, C is incorrect because having a higher speed does not necessarily guarantee the right-of-way. And finally, D is incorrect because going slower does not automatically give a vehicle the right-of-way.
