Some gas stations also offer repair services, indicated by the floating service icon. Using this service is just as simple. Simply drive over to the icon, stop the vehicle, and use the F5 key to repair as much or as little damage as you like. n.b. it is not possible to repair your cargo! The truck icon on the top-right of your HUD shows the truck damage level. As damage to your truck increases, the blue truck icon will slowly fill with red.
