You’re driving on a three-lane motorway. If studs to your left are red, and studs on your right are white, which lane are you in?

Explanation: Red studs are found between the hard shoulder and the edge of the carriageway, while white studs are found between lanes. Seeing red on your left and white on your right tells you you're in the left lane. Remember that green studs indicate a slip road, and amber indicates the central reservation. Bright yellow/green indicates roadworks.
