The correct answer is; Increase space.
Further Explanation:
It is important to increase the space between the van and other car when sharing the roadway. Vans are larger vehicles and will have a larger blind spot than other cars may have.
A blind spot is when the car in front of you can't see the traffic that may be behind them. This can cause an accident since the driver may change lanes rapidly or make a turn without a signal or brake rapidly. Staying father away from the van will also minimize tailgating that can cause an accident if the van is in an accident or brakes unexpectedly and the driver of the car can't stop fast enough.
