At first glance, the photos below are simply shots of a parked car with a speed hump in the background.
The images below show the speed hump in greater detail. Notice the curbing in the roadway at either side of the hump.
The final image shows the rear passenger-side rim of the car in greater detail. Notice that the tire is missing.
These photographs were taken in Vancouver - Clark County - Washington. The photographer writes:
"Here is the information about the car in the pictures.
" ... both tires were blown out and both wheels were bent. Drivers try to get as far over to the right as possible to avoid getting "bumped" harder, but, sometimes they get too far over and scrape their tires against the curbed edge of the 'planter boxes.'
[We...] "know of a dozen people who have blown out one or both tires. The car in the pictures was worse because the wheels were bent, too. Our county liability person says that the county is not liable for these problems because the speed bumps are properly signed."
And, the Telegraph (UK) reports on the damage and serious aftermath traffic calming curbing can have on tire safety in the article, "Calmed into a fury" by David Rudnick (September 5, 2000) -
"High-kerbed chicanes, for example, can be vicious predators on innocent drivers. The slightest misjudgement in fog, darkness or bright sunlight can cause serious internal damage to car tyres, increasing the possibility of a subsequent blow-out at high speed and a potentially fatal accident."
[RADA: We surely wish that NHTSA would pay attention to tire safety as well as the safety of Americans with disabilites.]
