All Interstate Trucks must have a shield around their fuel filters and fuel cut off switches if they can be hit by a broken driveshaft. This means all fuel filters and cut off switches on the inside of the frame must be shielded.

No batteries are allowed in the weight box of any truck class.

Any truck that throws excess oil on the track from blow by will be given 1 chance to correct it. If not corrected, you will be DQ'd at the next pull if it happens again.

These are safety rules.
