![]() The other reason for truck aprons is is they're not only found at roundabouts - they're also found at slip lanes. You can see here in the image that there's lots of black marks on the truck apron in this industrial area where the semi-trailers have gone up over that the apron. They take a shorter path and therefore they're going to run up over the truck apron. Off-tracking is simply the shorter path that the trailer tires take in relation to the steer tires. So there's two features that may deceive drivers, especially drivers of larger vehicles as to why in fact they can't go on the truck apron.īut the truck aprons are specifically designed for large commercial vehicles and are designed to compensate for the off-tracking of the semi-trailer. The second thing about truck aprons is that they are slightly elevated and the reason that they're slightly elevated is to try and keep cars and light trucks off the truck apron, and cutting off a shorter distance through the roundabout. In other words, it looks red from a distance and it's also because it's stamped with a pattern that looks like a paving stone - when in fact it is actually stamped, reinforced concrete designed to hold the larger weight of big semi trucks. ![]() The first is that it's coloured, stamped concrete. There's a couple of engineering features that might cause people to be deceived and commercial drivers to be deceived about why they can't use them. Roundabouts, are in fact, designed for big trucks, and the way that big trucks are accommodated with their larger size and off-tracking is with truck aprons.Įngineers designed truck aprons, but unfortunately the information about truck aprons has not been disseminated to the public for whatever reason. I'm talking to you today about roundabouts and truck aprons. I'm standing here at a big industrial roundabout just south of Armstrong, B.C., Canada.Īrmstrong, BC is 4, four-and-a-half hours northeast of Vancouver, British Columbia in the great country of Canada. Hi there smart drivers, Rick with Smart Drive Test - welcome back. We'll be right back with that information - stick around. So what we're going to do today, I'm going to talk to you about truck aprons. Unfortunately engineers have designed roundabouts for such purposes, but the public education hasn't been there. But I will tell you that roundabouts, whether you're in a car, a light truck, or you're in a big truck, or any large vehicle is a bit of a learning curve.īut roundabouts are designed for big trucks.Īnd truck aprons are specifically for that purpose.
