Meaning of slow vehicles?

Post by solocle »

Without an explanatory plate like the Nene Valley Way one ("vehicles not able to exceed 25 mph"), what does this sign mean!?

That sign means no tractor based diggers, I guess real tractors are permitted. A minimum speed limit would be better.

Question is could a minimum speed limit be time limited ? A1

These are special authorisation in both England and Wales, their exact meaning is what it says on the tin - agricultural vehicles and other slow moving vehicles using Rule 225 in the HC as the definition; anything that can't attain a speed higher than 25 mph and needs to display an amber beacon as per the Road Vehicle Lighting Regulations 1989 (Reg 17).

A minimum speed limit would be exempt from general traffic conditions, like congestion, so you would still be allowed to have tractors access these roads when such low speed conditions existed. There's a reason we don't generally bother with minimum speed limits.

USA prohibition signage is more sensibly "Vehicles incapable of ..." rather than a minimum speed limit.

Strangely considering the way they signpost them, US regulatory signs are a lot more concise and easy to work out - with one notable exception; parking signs. But that said I don't think any country on Earth can do a good parking sign.

Also I'd assume that minimum speed limits, like maximum speed limits, don't apply to non-motorised vehicles.

I mean, you're utterly screwed here on a bicycle. The no cycling sign on the right? Good luck seeing that until you're right on top of it. Then how do you comply!? If you stop, you contravene the clearway regulations...

TBF it looks apparently "possible" to get there but not necessarily sensible to put oneself in that position. There is a cycling prohibition sign on the N/B entry slip at Littlebrook but not at Princes Way or the A2 N/B slips. However the parallel cycle path is well signed to get you to the main control building for the lift through the tunnel.
Coming south there is a prohibition sign on the SB A1306 to A282 slip and the adjacent cycle path takes you to the control building and the free phone for a trip over the bridge that I used in about 2010.
As for slow vehicles, I have seen tractors use Dartford Bridge during the early morning.

Coming south the prohibitions are pretty watertight, although since "no cycling" signs don't have an "end" sign, what's to stop you just re-joining the carriageway from the cycleway... Possibly the "best" way to circumvent the restriction, however, is to take NCN 137 and make a wrong turn at Mar Dyke. There's a gate with the roundabout there which you could walk around, and no "No Cycling" signs, as the restrictions have already applied to the A13.

The circumstances that I can see riding across being useful would be when there's a gigantic traffic jam, which, given it's the Dartford Crossing, is hardly unusual. The shuttle service would get caught up in the jam, whereas it should be pretty easy to filter on a standard bike. Of course under such circumstances the bridge would be preferable to a tunnel...

However that would be transgressing S23 of the Dartford-Thurrock Crossing Act where crossing by cycle is prohibited although apparently not fully signed.

Yeah, I don't think it would fly if you did some obvious maneuver to circumvent the restriction. Simply following the hard shoulder of the A2, on the other hand...
