Just fell foul of one of these today.
It's autumn where I am and a very narrow one of these humps has been placed at the bottom of a long decent on the road home. I normally go around it, (between the gutter and the hump) as I find it's a lot less tricky. The thing with these humps particularly this one on this steep decent is it really tends to throw you forward so I avoid going over it. I've done this a gazillion times.
Today, slowed down, but failed to take in a huge wad of damp leaves just past the hump so went around it as usual. Normally a layer of leaves and chipseal is no probs but this was like hitting black ice - cue falling off, bruised shoulder, damaged flight deck shifter etc, sore lower back.
I'm p*ssed as this is on a semi private road that work is supposed to keep clean so I'm going to do an Health and Safety Incident form.
Anyone have experience of going over these?
