Bottom line is if you roll back on a hill during your road test, you fail. Using the parking brake routine will cause this not to happen. The true test is the driving the old klunker, they do this on purpose so if you can control the rattletrap , your ready for any of the other trucks.I have had long talks with our driver trainer and she has to be hard on everyone, since March she has trained 198 drivers. Traffic has changed and the risk factor is higher due to more people on the road, drivers texting, and not paying attention.
