This short video was filmed in Mansfield turning left at the traffic lights near the bowling alley and opposite the old bus station. This junction is one that catches learners out, the lanes are quite tight and people often misjudge their speed on the approach to the junction. This means they often go around the corner in a higher gear than would be ideal, then, due to the speed the control around the corner is more difficult and drivers often end up crossing into another lane.
You should take care on the approach to this junction and even if the lights are green slow down to safely proceed around the corner without encroaching on the other lane.
