Not to be pedantic but you do need to be able to see pedestrians at night too, who can legally walk on country roads on either side, without reflectors or illumination.

It’s the car drivers responsibility to not mow pedestrians down wherever or whenever they are walking.

Not least because hitting a person at 50mph on a country lane will cause serious amounts of damage to your car and ruin your day!

My point was that it is not pedestrians I worry about walking on the carriageway on a 60mph limit road, it's the trees
