A circular, roadside sign displaying the number “40” bounded by a distinct red ring indicates a mandatory prohibition-signifying what a driver must not do.

Peripheral hatching reduces vehicle speeds by around four percentage points; for example, if a vehicle is travelling at 30 miles an hour, it would normally reduce speeds by at least 1.2 mph. Reducing the width of lanes for motor vehicles decreases the feeling of space in the road, causing drivers to reduce their speed to avoid overrunning the hatched area.\u003c\/p\u003e\n\u003ch2\u003eNational Speed Limit Roundel Variations Available\u003c\/h2\u003e\n\u003cp\u003eWe supply speed roundel variations for different speed limit schemes, including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/readysetsupplied.co.uk\/products\/5mph-speed-roundel-tricolour?_pos=1\u0026amp;_psq=5mph\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e5mph\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/readysetsupplied.co.uk\/products\/10mph-speed-roundel-tricolour?_pos=2\u0026amp;_psq=10mph\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e10mph\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/readysetsupplied.co.uk\/products\/20mph-speed-roundel-tricolour?_pos=1\u0026amp;_psq=20mph\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e20mph\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/readysetsupplied.co.uk\/products\/30mph-speed-roundel-tricolour?_pos=1\u0026amp;_psq=30mph\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e30mph\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e40mph\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/readysetsupplied.co.uk\/products\/50mph-speed-roundel-tricolour?_pos=1\u0026amp;_psq=50mph\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e50mph\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/readysetsupplied.co.uk\/products\/60mph-speed-roundel-tricolour?_pos=1\u0026amp;_psq=60mph\u0026amp;_ss=e\u0026amp;_v=1.0\"\u003e60mph\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eEach type uses the same tricolour design and thermoplastic quality, giving consistent visibility and durability across every speed limit.
