Police radar controls everywhere at all times of day and night. Lawrence has plenty of stop signs to help you drive slowly. Orientation is simple. See getting around Lawrence . Most cars here are automatics.
P is for park, R for reverse, and D for drive.
Don't concern yourself with N, or D2 etc. You won't need them. You do not need an international driver's license . You can drive on your own country's for 90 days. And actually, I did that for 5 months.
