Biggest Driving Pet Peeve

[taiauberon]

Hmmm, big can of worms with this one.

My husband is a Commercial Truck Driver.  My biggest driving pet peeve is people who merge without looking.  I also hate people who drive too close to a commercial truck, or cut in front of them in traffic - they cannot stop as quickly as a passenger vehicle. 

If everyone would actually drive by the laws in place, it would reduce our congestion on the highways.
