You are going straight ahead. Are you obliged to yield the right of way to the vehicle approaching from the right?

In the video you are driving on a quiet street between houses and approaching a junction where no signs set the right of way; a red car is coming from the right. Going straight on, you must give way to it. The answer is: yes.

The Road Traffic Act states that a driver approaching a junction exercises particular caution and gives way to a vehicle coming from the right. The right-hand rule applies at every uncontrolled junction of equal roads, even when your street seems wider or more important. Fences and hedges hide the entry on the right, so you approach slowly enough to be able to stop.

Legal basis: Art. 25 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
