Oversize vehicles or vehicles carrying very large loads must have special signs mounted on them. They may also have pilot vehicles to warn other road users to take care.

If you see one of these signs or pilot vehicles when you're riding, you should slow down. If the oversize vehicle or load is coming towards you, you may need to pull over and stop to allow it to pass. Look for instructions form the pilot vehicle driver who may be holding a stop/slow paddle, a red traffic baton, or a red flag.

If the pilot vehicle is in front of the load, the sign will either say Long load follows or Wide load follows.

If the pilot vehicle is behind the load, the sign will either say Long load ahead or Wide load ahead.
