The lights are 'on the blink'. Use the Give Way rules for that intersection, and remember to be courteous to other drivers.
Wet and frosty roads can double the stopping distance, so use the four-second rule. The extra weight of a trailer will also add to your stopping distance. In fact, if it's frosty to icy, it can take you 6-8 seconds to stop.
On a road with lanes, you must be able to stop in the length of clear road you can see in front of you; on a road without lanes you must be able to stop in half the distance you can see in front of you.
It's only to allow you to stop safely in dry weather. If it's wet, apply the four-second rule. As regards overtaking, a vehicle should not overtake if the manoeuvre cannot be completed safely.
If a vehicle is indicating left you must not pass it on the left because there is a risk it will turn into your path.
Courtesy crossings are usually made of bricks or paving and are often raised above the level of the road. They are not official pedestrian crossings, but they do provide a place where drivers can stop safely to allow pedestrians to cross.
The legal limit is 0 milligrams per 100 millilitres of blood. A drink consumed before driving will almost certainly put you over this limit. So you must not drink just before driving if you are under 20 years old as there is a zero alcohol limit.
Even if you have priority on the bridge you must still give way to cars that are already crossing it.
If anyone is hurt you must report it within 24 hours to the police, and as soon as possible.
The lane is where you drive. A verge is the grass edge of a road. A pathway is where pedestrians walk. The road edge might have a kerb made from raised concrete or stone. Roads are marked with lines. Lanes are formed either between kerbs, verges, painted lines, a kerb and painted line or a verge and painted line.
It's white.
