Why do lorries and trucks

[4GS]

have an audible warning when reversing at 5MPH?
Wouldn't it make more sense to have a warning when it's moving forward at 70 MPH?

[redcrx]

they do! Its usually a very loud engine noise :)

Oh they have sirens, klaxons, bells and warning lights that go off when they reach 70. There is also a spring loaded boxing glove that thumps the driver.

However as European law requires speed limiters set at 56 mph you never see them.

(Incidentally there is no law requiring reversing horns, and many do not have them.)

The one that was reversing up my street at 4:30 this morning had one, the whole fcuking street was woken up by it

you should stop the driver next time and ask politely if in future they can drive at 70mph and then do a handbrake turn, thus avoiding a reversing manoever. Thats got to be safer than having to go backwards with limited vision. :)

He was breaking the law using a reversing horn at 4.30 am in a residential area
