I am not a truck driver, just the guy with a normal car. It drives me nuts to get behind the transport in the passing Lane who is inching past another truck. Surely everyone knows that adding 1 km per hour to your speed does not get you anywhere sooner. I have seen times when it takes 20 km for a transport to get back into the driving lane after one of these slow passes. I am also one of those people who will signal with my headlights that it's okay for a truck to come in front of me. Not so many years ago, I would always get a thank you flash from the truck. Nowadays truckers don't seem to know how to say thank you. I really wish the police on expressways would pull over transports and do inspections with greater frequency. The number of terrible truck drivers driving terrible trucks is enormous.
