You have stopped temporarily at the side of the road. Which statement is true when you want to rejoin the road?
In this example, this rule applies to you:
“A driver may only start from the side of the road [...] if it is possible to do so without causing a hazard or an obstruction to other road-users.” (Road Traffic Ordinance)
The priority-to-the-right rule does not apply when your car is stationary at the side of the road. Neither is this classed as a changing of lanes, because the side of the road is not a lane. You will be ‘starting from the side of the road’, and must therefore comply with the legal text above.
There is also a driving licence book online (2022).
