Are there specific safety rules or guidlines for using traffic cones behind a broken down vehicle?

Question

I am doing an NVQ in Large Goods Vehicles and training for my Class2. It's something that I had to do recently whilst out on the road, and felt uncomfortable not knowing whether I had spaced them properly! I'd like to be more sure the next time it happens!

Answer 1

I don't think there is a regulation but i do know if a vehicle is travelling at  55mph it requires a 5 sec warning which is 150 yards in distance  so if you use that as a bench mark for your cone you will not be far out.

Just alter the distance of the cone to the speed limit of the road

Hope this helps

Answer 2

On a two lane or undivided highway, place reflective triangles on the traffic side of the vehicle within 10 feet of the front or rear corners.

This marks the location of the vehicle. Additionally, place reflective triangles about 100 feet behind and ahead of the vehicle on the shoulder or in the lane you are stopped in.

If you are stopped beyond any hill, curve, or other obstruction that prevents other drivers from seeing the vehicle within 500 feet, place reflective devices at 100 to 500 feet behind.

If you are stopped on or by a one-way or divided highway, place reflective triangles 10 feet, 100 feet, and 200 feet toward the approaching traffic.

Answer 3

yes,there is a minimum space a warning triangle needs to be placed behind a broken down vehicle. not really sure what it is but it will tell you in the highway code.
