Over the last 20 years there has been a steady trend away from ‘all motors’ permanent prohibition of driving orders on ‘green roads’ towards limited, and problem-specific, orders, which aim not to restrict lawful traffic more than is essential. Such orders include provisions for:

• Permit access for residents and recreational users.
• Seasonal orders, prohibiting all, or heavier, vehicles in the winter months (on  the basis that these are wettest). In general seasonal orders are enforced by  locked gates and appropriate statutory signs to prohibit 4x4s whilst  motorcycles pass via the ‘horse gap or gate’.
• Weekend prohibitions. Such was used to balance vehicular traffic on the  Great Ridgeway against peaks on non-vehicular traffic.
• ‘Open day’ exemptions from otherwise permanent prohibition of traffic orders. The order is expressed to be in force except on days by agreement with the  highway authority, and is normally enforced by a locked gate. Motor cycles are normally exempt.
• • ‘Locked gate’ orders. A permanent TRO is in force, but operational only when a gate is locked in bad weather. Motor cycles are normally exempt.
• Width restrictions.
• Weight restrictions.
• Wheel (number of) restrictions.
• Type of vehicle restrictions (e.g. specifically exempting ‘quads’ from an order that prohibits ‘cars’.
