On the right shoulder driving is permitted in order to stop, stand or park the vehicle; to accelerate before entering the travel lane; or to decelerate before a right turn. Using the right shoulder is also allowed when passing another vehicle that is slowing or stopped in the travel lane or about to turn left, or to let a faster vehicle pass.
Drivers also have the option to use the right shoulder to avoid a collision or when required to by traffic-control devices, such as construction barrels.
On the left side, driving on the shoulder is permitted in order to slow or stop a disabled vehicle that cannot reach the right shoulder, to avoid a collision or when required to do so by traffic-control devices. Police and emergency vehicles and cyclists are not subject to those rules.
