Yeah, you never know when you will get pulled in. For anyone reading this, all trucking companies are in a data base with past performance ratings. If your company gets a lot of write-ups, it's in the data base and you will be "chosen" for an inspection more often as opposed to a company that has minimal write-ups.
Also, DOT inspectors look for telltale warning signs, such as a cluttered dashboard, dirty truck, half ass mud flaps, low hanging air lines on the trailer, not working clearance lamps etc.
Also, do not enter the scale off ramp/and or cross the scale going too fast. If it's a WIM (weigh in Motion) just do the posted speed. Pre-pass helps, but is not a guarantee to get you through.
Whenever you stop, update your log. AND, BE COURTEOUS. Jimmy
