DO NOT SET BRAKES!
Front wheel drive car, front wheels on dolly. Transmission in PARK
, emergency brake (rear wheels) OFF
. If your dolly has a pivot plate the front wheels rest on, steering wheel should be locked or restrained with seat belt or strap to remain straight. If you don't have a dolly with a pivot plate, the steering should be unlocked to allow car to 'bend' to go around corners. Make sure there is clearance between dolly fender and car sides for car movement. Check dolly owner's manual to be sure.
After driving around a few corners, stop and retighten the straps holding wheels on dolly, they stretch a lot, especially when new. You will soon figure how far you can travel between stops for strap tightening!
