Because of their vital importance and sensitive nature of those that they aid to smoothly convey from one end of an incline to another, outdoor wheelchair ramps have certain rules applicable to them. They relate to size, construction criteria, positioning and height. These rules are meant to make them convenient amenities that can offer competent, safe and reliable utility for the disabled.

This is why they are required to be of a certain size that can fit the place in which they are laid on. They should neither be too narrow or wide for the platform since this will either restrict movement or cause accidents. Similarly, the platform should be of a size and weight that can accommodate the wheelchair and the person traversing on it.

In terms of height, certain jurisprudences only allow certain heights for outdoor wheel chair ramps being used in public places. The angle of incline is also fixed to make them safe for both the user and other persons walking close to them. If they are set near the stairs the angle of incline should only be equivalent to that of the stairs or less. The space should also be wide enough to allow room for the vehicle inside to pass while leaving some room for walking.

The nature of construction is another high priority considered by local authorities. They stipulate that such a structure should be built by any of these materials: wood, aluminum or steel. Though, they should be strengthened to make them less slippery during rain. They are certified to have a gentle incline for drainage of water gathered during rainy conditions. Outdoor wheelchair ramps also require hand rails on which to hold and keep balance and overall convenience. They also act as armrests for the treed user. Protective edges are also required to act as safeguard against falls.
