284 It is better to restrict vehicles at a place where they can choose another route,
or at least where they will not need to reverse or manoeuvre in a tight space when
they find out that they can’t go ahead. Width and height restriction posts can be
very effective for this.

about vehicle weights, and Signs, signals and markings (paragraphs 393-402) for
more information about signs for hazards.
286 You need to understand how much space is needed for the vehicles that move
around your particular site, and make decisions about how much space they need.
287 Steep gradients can make handling vehicles difficult, especially if the surface is
made slippery (for example by a spill or by poor weather). Slopes also affect how
easily spills can be contained, and how easy it is to manage wheeled objects such
as waste containers, roll cages or pallet handlers.
288 Some vehicles can become unstable on slopes. Examples include some lift
trucks, raised-tipper lorries, raised-body tankers involved in transferring powder
or bulk solids, and vehicles with a trailer containing liquids (such as a bowser or a
slurry tanker) but without effective baffles to stop the liquid surging around.
289 Steep slopes can also make loads less stable, especially if they are stacked
or if they are unstable anyway (for example, wire coils or reels, barrels). You should
take care that loads are not able to move dangerously if they are being moved on
slopes.
290 Even where vehicles can safely use sloping surfaces, slopes steeper than 1 in
10 should be avoided.
291 There is information about the construction of slopes on traffic routes in
Construction of traffic routes in paragraphs 319-337.
