If you are pulled over in traffic, pull off to the right only. Look for a safe place to pull over, well lit and out of heavy traffic.
Do not get out of the vehicle unless the officer requests it.
Have all of your paperwork in order, BOL's, permit book, etc. However, only give the officer what he or she asks for.
Remember the two Rs - respect and respond. Convey a receptive attitude: anger, hostility and sarcasm never help.
