Drive, drive, and drive some more. Driving experience is huge. Any little bit of experience helps. Even small trips, like driving with your parents to the grocery store. The more exposure you have to being behind the wheel, the more confident you’ll become.
Warm up those driving muscles before the road test. Do some last minute practice, like parallel and reverse-stall parking. Getting to your exam location from behind the wheel can be a big confidence booster. Also, plan to arrive at least 15 minutes prior to your appointment time. Leaving it too late can increase your anxiety and not leave you in the right frame of mind to be at your best.
Keep yourself to the posted speed limits (not with speeding traffic) and keep a safe distance from other vehicles. Make full stops at stop signs, scan intersections, and be aware of potential hazards. Mirror check, signal and shoulder check whenever you change lanes or direction. Also, watch for school and playground zones.
