What can I expect at a tech inspection?

Cars are checked for safety at each event before your first run. Generally, this task falls to an experienced autocross driver and the inspection is friendly. Your car must have a working seat belt, a good return spring on your throttle linkage, working brakes, a securely fastened battery, tight lug nuts, well-packed bearings, no excessive play in your suspension, and an interior free of loose articles. Street tires must have measurable tread depth and no cord showing. Any street car in reasonably good condition should pass this quick inspection without any trouble.

Cars are inspected ("tech'ed") at a specific tech area before being allowed on the starting grid.
