A small convoy of truckers demanding an end to coronavirus mandates began a cross-country drive from California to the Washington, D.C., area on Wednesday.

Several hundred people rallied in a parking lot in the cold, windswept Mojave Desert town of Adelanto before about two dozen trucks and a number of other vehicles hit the road. It wasn’t clear how many intended to go all the way. “To the truck drivers around the world: Now is your time to stand up. Now is your time to usher in a renaissance time of freedom,” truck driver and event organizer Brian Brase told the rally. “Do not bow down.”
