The white car is leaving a petrol station to join the traffic flow — if necessary, when must it give way?

When joining a public road from a service area, we must give way to vehicles travelling on that road, whether they are approaching from the right or from the left. As a general rule, joining from a stopped or parked position, from a service area, or from an adjacent property must be carried out: - Without obstructing other drivers and road users, to whom right of way must be given, taking into account their position, trajectory and speed.
- Without causing those approaching in motion to swerve abruptly.
- At an appropriate speed.
- Without posing a danger to other road users.
