1.3 All USMTS racecars are subject to inspection by a USMTS Official at any time.

1.4 Approval of any USMTS racecar by USMTS Official shall mean that the vehicle is approved for participation in a competitive event and shall not be construed in any way to mean that the inspected vehicle is guaranteed mechanically sound or safe. Be it further declared that the USMTS Official shall not be liable, nor shall the USMTS, for any mechanical failure nor for any losses, injuries or death resulting from same.
1.5 Drivers, owners and crewmembers will conduct themselves as professionals.
