Which is the safest way to turn if two cars are turning right onto a crossroads?

Answer: B — offside to offside

If two cars are turning right onto a crossroads, the safest way for them to turn is offside to offside. This means the right side of each car should be closest to the center of the crossroads. This allows for maximum visibility and avoids the risk of colliding with the other car. Nearside to nearside turning (option A) may obstruct the view of one car and increase the chances of an accident. Parallel turning (option C) is not recommended as it increases the likelihood of the cars merging into each other's lane. Option D is not a safe option as both cars should not turn at the same time in order to avoid a collision.
