The winter driving season in B.C. is October 1 to March 31.

Winter driving: Are you prepared?

Every day in B.C. drivers are at risk of being injured or killed while on the road. As the weather changes from fall to winter, the chances of being involved in a crash dramatically increase.

Winter driving can be hazardous. Rain, snow, ice, sleet, fog, and limited daylight hours present real challenges to motorists, whether they drive for work or pleasure. In fact, when it comes to winter, the number of casualty crashes in which someone is killed or injured due to driving too fast for road conditions almost doubles from 114 in October to 222 in December.1 In addition, more work-related vehicle crashes causing time-loss injuries occur between October and February.2

NEW: Free online Winter Driving Safety course for employers and supervisors

The new online Winter Driving Safety course will provide you with the tools you need to plan, implement and monitor a winter driving safety program in your organization. The course features practical information on reducing the risks associated with winter driving including:

  • How to develop winter driving safe work procedures and a safety policy
  • Ways to communicate with workers about winter driving safety
  • How to monitor and evaluate winter driving practices

The course takes approximately two to three hours, and you will be able to download or print a certificate of completion for your records at its conclusion. Additional tips and resources on how to prepare yourself and your vehicle and how to drive safely on winter roads can be found at


  • Know before you go. Check road conditions beforehand at and ask yourself: Do you really need to drive during inclement winter weather?
  • If you have to drive, then drive smart. Prepare yourself. Prepare your vehicle.
  • Always drive for the winter conditions. The posted speed limit is set for ideal driving conditions. Can you recognize and respond to road hazards such as black ice, snow, rain, low light, and fog?

Safety tip…

Get your care ready for winter by ensuring your battery, brakes, lights, and fuses, cooling and heating systems, electrical and exhaust systems, and belts, hoses, and wipers are in top shape.

landscapeAir is 78 percent nitrogen, just under 21 percent oxygen, and the rest is water vapor, CO2 and small concentrations of noble gases such as neon and argon. We can ignore the other gases.

There are several good reasons to use pure nitrogen in tires.

The first is that nitrogen is less likely to migrate through tire rubber than is oxygen, which means that your tire pressures will remain more stable over the long term. Racers figured this out pretty quickly that tires filled with nitrogen rather than air also exhibit less pressure change with temperature swings. That means more consistent inflation pressures during a race as the tires heat up. And when you’re tweaking a race car’s handling with half-psi changes, that’s important.

Passenger cars can also benefit from the more stable pressures. But there’s more: Humidity (water) is a bad thing to have inside a tire. Water, present as a vapor or even as a liquid in a tire, causes more of a pressure change with temperature swings than dry air does. It also promotes corrosion of the steel or aluminum rim.

If you ever need to top off a tire when you’re out on the road, It’s a good idea to briefly depress the tire chuck’s valve with your thumbnail and vent some air. If your thumb gets wet, there’s water in the line. Some gas stations don’t do a very good job of keeping the humidity out of their air system. I don’t even like to use a water-based tire-mounting lubricant unless I can let the tire bake in the sun for a couple of hours before I air it up and seat the bead. I’ve dismounted tires (not mine) that had several quarts of water inside—probably from a compressed-air hose that collected water and was never purged properly.

How is water relevant to a nitrogen discussion? Any system that delivers pure nitrogen is also going to deliver dry nitrogen. Filling tires with nitrogen involves filling and purging several times in succession, serially diluting the concentration of oxygen in the tire. This will also remove any water.

NitrogenTankIt’s certainly simple, although time-consuming, for a tire technician to fill and bleed tires. We use a machine that not only generates almost pure nitrogen by straining the oxygen out of shop-compressed air, but will also automatically go through several purge cycles unattended. Some shops have been charging as much as $30 per tire for this service. I think that’s too much. If you’re buying a new tire, it should be far less. Still, the nitrogen generator filling system and technician’s time aren’t free, so the shop should be entitled to some return.

At Canadian Power Machines, nitrogen is included with your tire purchase, but there is a reasonable charge for anyone simply wanting to take advantage of nitrogen vs air in their own tires.

  • With nitrogen, your tire pressures will remain more constant, saving you a small amount in fuel and tire-maintenance costs.
  • There will be less moisture inside your tires, meaning less corrosion on your wheels.
  • You will not be able to feel any difference in the ride or handling or braking, unless your tire pressures were seriously out of spec and changing to nitrogen brought them back to the proper numbers.

Increasing Mileage – Lower Your Fuel Costs…

With fuel prices rising as much as 200% in the last 4 years we are changing the way we drive. Larger less efficient vehicles are losing value and smaller vehicles are the norm on the highway these days. Being one of the many who need a larger less efficient vehicle to use for day to day activities such as hauling equipment, tools, or just garbage I have to maximize my fuel usage and try to improve the efficiency of my truck.  Using a programmer and other aftermarket add-ons such as larger free flowing exhaust and a cold air intake my power and mileage both went up noticeably on the diesel engine. Gas engine vehicles can benefit from the same add-ons as well as new tune-up techniques that will improve power and economy substantially.

Call us at the shop and we can customize a plan to get the most out of your gas guzzler. Many of our customers are offering us proof of the mileage gains within the first tankful of gas and most have noticed substantial power gains. Most of what we are doing is considered regular maintenance so the only thing you really have to lose is more money at the pumps.
