All Iowa DOT business locations will be closed Jan. 21 in observance of the Martin Luther King Jr. holiday. All Iowa DOT driver’s license stations, normally open Tuesday through Saturday, will be closed Jan. 19 in observance of the holiday. Normal business hours will resume at 8:30 a.m. Jan. 22.

The Iowa DOT’s Office of Vehicle and Motor Carrier Services’ permit center will be closed Jan. 21. The permit center will resume normal operations at 8 a.m. Jan. 22. Because the Office of Vehicle and Motor Carrier Services typically experiences a heavy workload on the day after a holiday, customers are urged to submit applications for oversize permits, especially those weighing more than 156,000 pounds, several days before the permit is needed.
