Near Serooskerke you see well in advance that your lane is ending because of roadworks. What is the best thing to do?
Adjust speed around 300 m, keep driving on the ending lane, and only actually merge around 50 m
Merge immediately as soon as I see the sign, well before the narrowing
Explanation
Wrong — trap: early merging confused with the official zip-merge sequence. Use all available room: adjust speed at 300 m, only actually merge at about 50 m (Book p.155).
