Where an HGV strikes a bridge, the DVSA will investigate the company involved and both driver and operator could face criminal prosecution. i) a marker on a side of the load is fitted in the prescribed manner if at least part of it is within 50 mm of a longitudinal plane passing through the point on that side of the load which is furthest from the axis of the vehicle; and Furthermore, drivers should be made aware of road signs and what they mean – if a vehicle is higher than shown on a circular (prohibition) traffic sign, the sign should not be passed. You would be very likely to collide with a bridge and be prosecuted. Are you one of the 32% of HGV drivers who don’t know your vehicle’s height? In-cab height indicators can be bought online however most vehicles tend to have them included by the manufacturer. The table below is a summary of the requirements applicable to loads overhanging the sides of a vehicle as set out in regulation 82 of C&U. Load projection or overall width

Must admit I considered the approach of using trig from the comfort of the cab, but you'd have to be able to see the peak of the uneven load from two adjacent sides (peaks occurring toward the middle of the container and which only modestly exceed the height of the container, may not be visible on two adjacent sides at any reasonable distance), the peak would have to be occluded by the container at not-too-close an angle (i.e. if the peak is near to the edge of the container and clearly exceeds the height of the container even at close range, so that it is only occluded at an angle close to 90 degrees, then it would have to be measured directly to avoid an excessive margin of error), and you'd have to take all observations on a completely level area (because you have no tools capable of correcting for uneven ground), and the top of the container itself would still have to measured and would have to be completely level around its perimeter relative to the ground (or be measured at all the points where it coincides with the lines of observation). iv) it, and any means by which it is fitted to the projection, impedes the view of the driver as little as possible, andThe right angle fold out arm at the top enables drivers to accurately measure vehicles, loads or an obstruction ahead. Measurements are shown in both imperial and metric. At least one person in addition to the person or persons employed in driving a motor vehicle to which this

a) Subject to subparagraph (d), every load carried on a vehicle in circumstances where this paragraph applies shall be fitted on each side and in the prescribed manner, with— Different manufacters seem to have different 5th wheel heights. Unless drivers are dropping them intentionally like this. Follow all local regulations and guidelines for measuring the height of HGV vehicles, including any specific procedures or safety protocols.Two clear working days notice to Police ( C&U schedule 12, para 4), Marker boards front and rear ( C&U Schedule 12, para 3), Additional lights required during hours of darkness or poor visibility v) in a case to which regulation 82(7) and (8) applies, the overall length of the vehicle and the length of any forward or rearward projection of the load or special appliance or apparatus.

The Chief Officer of Police for any police area may, at his discretion,accept a shorter period of notice or fewer details. iii) the vertical distance between the lowest part of each marker and the surface of the road is not more than 2.5 m,iv) in a case to which regulation 82(4)(b) applies, the overall length of the combination of vehicles and the length of any forward or rearward projection of the load, and c) where the forward projection exceeds 2 m or the rearward projection exceeds 3 m, one side marker shall be fitted on the right hand side and one on the left hand side of the projection so that— If an articulated lorry is pulling a trailer and the trailer is switched during a journey, the OTH may need to be recalculated as follows: I sometimes have to wind legs up slowly if a trailer is dropped so low I struggle to get under it even with air suspension all the way down. And sometimes need to lower a trailer if it's been dropped and is too high. With an average occurrence of 5 bridge strikes a day, hauliers across the UK face losses of millions of pounds a year. Ensuring that drivers know their HGV height limit and plan routes accordingly therefore has to be a priority for the industry. Are you HGV height aware?
