Up here, if you break down or have an accident (whether it’s your fault or not), being stranded by the side of the road means you (and everyone else you’re travelling with) are at risk of getting extremely cold or being hit by one of the massive long trucks loaded with logs we saw charging along these roads. It is always advisable to travel with warm clothes, a mobile phone, a decent torch and a European Travel kit (as legally required). In these conditions especially, I would probably put the warning triangle out further behind than ‘normal’.
They have to watch out for reindeer on the roads too. Hitting Rudolph would not only cause a bad impact on you and your car, but might also hamper the distribution of joy and goodwill next Christmas.
Other tips included keeping your car’s lights clean so you can see and be seen, avoid sudden steering wheel movements or heavy braking, and always leave extra room to stop at junctions and to pull out again so you aren’t tempted to try to accelerate or brake too hard and lose traction. It all makes good sense, and certainly shows that life goes on as normal in Lapland despite all the snow and ice.
We did comment at how fast some of the locals drive on these roads. I guess they have the experience and confidence to do it (and sometimes studded tyres). Our own confidence at towing on roads of packed ice and snow improved vastly during our time in Finland. Fitting winter tyres to the car, caravan and motorhome was definitely a huge help (and a legal requirement here). They have Nordic winter tyres in Finland designed for their extremely low temperatures.
