Level 1 inspection from pump,down test to complete pre- trip including fuses in the Ash tray. He measured push rod length on all chambers also checked Tire pressure on tires.He was a young officer with a seasoned officer with him.Both were extremely nice to driver and advised driver to get letter from a dr.for tint exemption.As I told driver's before be polite and do as they say because the truck will pass any dot check but will the drivers attitude???
