In this situation, when making a U-turn you must give way to

Explanation

Only to the oncoming passenger car.

The yellow diamond beside the road shows that you are on the priority road and that the road on which the tanker lorry is standing is minor. Your left indicator is on and you intend to make a U-turn, that is, you must cut across the entire width of the carriageway and return in the opposite direction.

When making a U-turn there are two separate duties. First duty: give priority to vehicles coming from the opposite direction on that same priority road; that means the dark passenger car facing you. The second duty does not arise here at all, because the lorry is entering from the minor road and is itself obliged to give priority to any vehicle travelling on the priority road; so you do not give way to it.

The safety reason is clear: a U-turn is the slowest and longest manoeuvre at a junction, and the car stays crosswise and without speed in the path of the opposing flow for a long time. That is why the law does not permit this manoeuvre to cut into oncoming traffic. The exam trap is the tanker's size and closeness; but its position on the minor road creates no priority. Practical point: before starting a U-turn, make sure you have enough space and will not have to correct with reverse gear in the middle of the manoeuvre.

• This adds the tanker lorry as well; but that lorry is on the minor road and, by the priority-road sign, must give priority to you, not the reverse.
