We should pay special attention to bridges and overpasses when driving in temperatures around the freezing point. Over the years we have heard that bridges may be icy while the road is not. We have also seen signs posted before bridges and overpasses which state this for safety reasons. This condition however is an important one that should be given some consideration. So how could the bridge be icy when the road is not? Here’s why.
Topic: Winter driving tips
The first winter storm of the season often catches many of us by surprise. Soon most of us will have had our first big burst of winter weather. The snow-covered roads and plow trucks are an obvious indicator that we should be vigilant while driving. But what about when ice is present without these visual cues? Black ice is the winter threat many of us fail to observe until it’s too late.
Friction and traction are key to avoid sliding vehicles and spinning wheels.
Friction is defined as the rubbing of one object or surface against another. The friction between your vehicles’ tires and the road will determine maximum acceleration and minimum stopping distance. The force of friction depends on the force pushing the objects or surfaces together and the coefficient of friction. The coefficient of friction is the relationship between the force required to move the surfaces against each other and the pressure to stay in contact while in motion.
Guest Blog, no 2 from the Haaks
After quite some vacation we’re on tour again! In a way, the winter is our favourite season when we perform in the different ski resorts, and the audiences are always wonderful. Our first week of the tour was spent in the classical hotel Sälens Högfjällshotell, in Sweden. The sun was shining, the slopes were filled with skiers, and already by four o’clock, the after ski was crowded with partygoers. A very special thing about this week was us co-arranging a corporate event, resulting in 250 happy hairdressers on the show.
Although Onspot automatic snow chains are mostly used in transportation trucks and rescue vehicles, of course there are other users who also need to make it in time. This week’s guest blogger, Jonas and Henrik from the Haaks band, points out that also showbiz has the very same need. Enjoy! / the Onspot team
Preparing for winter road conditions
We’re Haaks, a show band who have been playing full-time for the past 24 years. It’s me Jonas (bass & vocals), my brother Johan (guitar & vocals), Mattias (keyboards), Roger (drums) and me Henrik (sound & light).
From being mostly a night club band, we’re now doing more and more company events and happenings. Especially, we look forward to the after beach gigs in the summer and the after ski gigs in the winter. Nothing compares to entertaining people who are on vacation. Summertime, we’re mostly in Swedish Tylösand and Tanumstrand and wintertime is mostly about Swedish and Norwegian ski resorts. All gigs also mean that we spend a lot of time out on the roads and it requires good planning.
We all know that friction and traction is crucial to avoid sliding vehicles and spinning wheels. (To learn more, read the blog post What is traction, friction and road grip?) When driving, we have a sense of whether road friction is high or low. But is there a measure for road friction? If so, how could that be calculated since there are several different variables summing up as road friction? Let’s have a closer look at this “road friction”.
We should pay special attention to bridges and overpasses when driving in temperatures around freezing point. We’ve learnt that bridges may be icy while the road isn’t, and that’s all we need to know to for safety reasons. But, giving it a second thought, how could the bridge be icy when the road isn’t? Here’s why.
Whether driving a small go-kart or a heavy hauler, you must have traction to move forward. Actually, you can’t even walk without it. Traction is a commonly used word and many believe it’s just another word for friction. But is it really? Let’s have a closer look at friction and traction – what it is and why it’s so fundamental to safe driving.
We all know the feeling when tyres lose grip and the vehicle starts skidding. Controlled skidding in a go-kart could be fun, but a heavy vehicle unexpectedly skidding on a road could cause a very dangerous situation. The skidding is due to the vehicle losing road grip and obviously, this has to do with tyres and road surface.
It comes every year, but it surprises us every time and often poses severe problems – of course we are talking about the winter. Everyone involved in the transportation industry knows that a lack of road maintenance and poorly equipped trucks can cause major problems and increased costs. We cannot influence the weather but we can adapt our business to the weather and to the slippery conditions.
Properly equipped vehicles adapted to different weather conditions and recommendations or laws may be crucial to ensuring that the shipment can be delivered as agreed. Many countries also have legal requirements for both winter tires and snow chains.
