Superior Auto Body Saskatoon has been in business since 1961, and we have been an SGI ELITE Autobody shop and have been SGI accredited since 1982. There are many reasons we have so many loyal longstanding clients from all over the city, but mostly it is the small, personal touches that we offer to people who have been unfortunate enough to require our services. We offer newer model courtesy cars and vans for our clients..and to help out we will also pick up your vehicle and take it to your SGI appointment for you and deliver the courtesy car to you at home. In our latest blog post, we discuss …In our latest accident prevention tips, we share info about Danger zones for semi-trucks.
Our team at Superior take pride in their workmanship… as we always say, “When we get through it’s just like new”.
At 30 km/h a truck can stop – just!
The truck is approximately three and one-half car lengths from the crosswalk when the driver sees the pedestrian. Under ideal conditions, the driver may be able to stop just in time.
At 50 km/h, the truck cannot stop in time!
Even under ideal conditions, the driver of the truck cannot stop in time!
Both the pedestrian and the car on the right are about to enter the danger zone!
The distances in the diagrams are approximations only for illustration, as braking distances will vary according to the weight of the vehicle, the condition of the brakes and the condition of the road surface.
When conditions are less than ideal, commercial vehicles, like passenger vehicles, can decrease their stopping distance by reducing their speed.
If another vehicle or a pedestrian should enter the danger zone, the driver cannot stop the vehicle in time. It is not physically possible. So be aware of this and note it as vital accident prevention tips
Shrinking the danger zone for semi trucks
The illustration of the danger zones shows how the distance is shortened if the speed of the vehicle is reduced.
The zone can also be reduced if you form the habit of “covering the brake” when you recognize potential danger developing. In the previous diagram, the driver has recognized that he/she is nearing an intersection which is a danger spot. The driver knows the line of cars on the right may hide hazards from view. The driver removes his/her foot from the accelerator and places it lightly on the brake. When the driver first sees the hazard, the reaction time has been reduced because the driver removed his/her foot from the accelerator. Therefore, the stopping distance has been reduced and he/she now has a better chance of stopping before the crosswalk, rather than across the intersection.
Speed, weight and stopping
|If the vehicle’s:||Then to stop, you need:|
|weight is doubled||double the braking force|
|speed is doubled||four times the braking force|
|weight AND speed are doubled||eight times the braking force|
