Impact, Texas regulations require all heavy haul operations to comply with the Texas Department of Transportation (TXDOT) guidelines as well as local ordinances administered by the Impact Department of Transportation (IMPDOT).

Heavy haul permits are required for any load exceeding 11 feet in width, 13 feet 6 inches in height, or 152,449 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Impact, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Impact Bridge and the vicinity of Impact Convention Center, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

Texas law mandates escort vehicles for any load exceeding 15 feet in width or 13 feet 6 inches in height. When traveling through Impact, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Impact Department of Transportation requires a minimum of 26 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Impact.

The Texas Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from Impact Department of Transportation for transit through Impact limits.

Required documentation for Impact permits includes axle configuration diagrams, proof of insurance with appropriate coverage levels, and detailed transport plans. Engineering assessments may be required for loads exceeding standard weight thresholds on certain streets and bridges.

Impact has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Impact Film Exposition and the the Impact Cultural Convention, which may impact routing and scheduling.

Certain neighborhoods, such as Impact Center and areas around Impact Lake, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.

The base permit fee for an oversize load in Texas is $40, with additional fees for super heavy loads (over 200,000 lbs) ranging from $150 to $350 depending on the complexity of the move.

For movements within Impact, Impact Department of Transportation may charge additional fees for city-specific permits, which can range from $75 to $500 or more for particularly complex routes or those requiring extensive coordination with city agencies.
