Beware of speeding, careless truck drivers. Some are so pressed for time that they go way above the speed limit, 55 in California. I was just getting ready to pass this truck on an incline when he suddenly swerved in front of me without ample warning, endangering others. I used to be an examiner at the DMV, so nothing infuriates me more than observing a careless truck driver such as this one. Final score: FAIL.
