Examples of past tech issues that cause problems are:
1 loose battery
2 stock seatbelts cannot be more than 20 years old
3 5 (or more) point belts must be 5 years old or less.
4 loose wheel bearings
5 Sound - 92 db max
Well, you get the idea. Pre tech simplifies things on the day of the event, plus you have more time to get ready rather than spending it in a tech line that you need to be in before 7:30 am
(Note to tech inspectors: Somehow, I didn't mention tires, did I?)



NOT!
