District of Columbia Weigh Stations & Ag Inspection
The District runs no interstate weigh stations, so there's no OPEN ramp to pull into and no PrePass or Drivewyze bypass to earn. DC enforces truck weight with portable scales and weigh-in-motion on its posted truck routes, worked by MPD and DDOT; you stop when an officer flags you. Commercial trucks are also held to designated truck routes, off residential streets. Overweight and off-route fines are steep, so carry your permit.

- Where the stations are: No interstate fixed weigh stations. The District enforces weight with portable scales and weigh-in-motion on posted truck routes, worked by MPD and DDOT. There's no OPEN ramp to watch for; you comply when an officer directs you to a portable scale.
- Bypass: Not offered. The District runs no fixed weigh stations, so there are no PrePass or Drivewyze bypass sites and neither program plays a role inside DC.
