At a junction in Nijmegen you want to turn right. Just before turning you glance once in your right wing mirror: no cyclist visible. What is the correct next step before you actually turn?
Turn immediately; the mirror would already have shown the cyclist if there was one
Still look separately over your shoulder — a cyclist may have moved into the blind spot in the meantime
Explanation
False — trap: mirror glance treated as a complete check. A cyclist beside or behind-right of you can slip into the blind spot between that glance and the turn; look separately over your shoulder (CBR teaching material/Driving procedure B).
