For some reading this, winter may just have begun; for others, you may be well into winter. For new and seasoned apparatus operators this can be a very challenging time, to say the least. But questions come to mind: "What has your fire department done to prepare new apparatus operators for...

- Braking— Start braking sooner than you would under normal driving conditions.
- Speed— Slow down! No one should expect the apparatus to show up in the same amount of time with six inches of snow on the ground versus dry pavement.
- Steep or long grades — Know your response area, slow down long before arriving at a steep or long grade, have the apparatus in the lowest gear and cover the brake. Always have a way out.
- Slippery pavement— On slippery, snowy or icy pavement, reduce your speed, drive slowly and with a heightened state of situational awareness.
- Winding and narrow roads — Keep well to the center of the lane; do not drift off the edge of the road. Drive slowly and scan ahead as far as you can.
- Corners — Slow down well in advance of the corner. Understand that the weight of the vehicle pushing you forward may well overpower your ability to maintain traction, control and steer the apparatus; it may just go straight.
- Turning — Slow down and signal your intentions long before the turn to warn others around you. As with cornering, understand that the weight of the vehicle pushing you forward may well overpower your ability to maintain traction, control and steer the apparatus and it may just go straight.
- Losing control when cornering — Most defensive-driving experts will advise you to steer into the turn, although human nature may have you react differently.
- Intersections — When approaching an intersection that has a green light, slow almost to a stop and understand that civilian drivers may not be able to stop in the snow or on the ice, regardless of the color of the light (Figure 1). When approaching a red light, come to a complete stop and make sure that all civilian drivers have stopped, are granting the right of way to you and are not going to slide into you.
- Auxiliary braking systems — When I drove in the snow, I would leave the engine brake on as long as I maintained traction and it would actually help me control and stop the vehicle. However, on ice, I would turn the engine brake off not wanting it to throw the apparatus into a skid or spin. Today, I would guide my actions based on the recommendations of the auxiliary brake manufacturer. This information is generally found in the auxiliary brake manufacturer's operators manual.
- Apparatus maintenance — Tires must have 4/32 inches of tread depth and should be mud-and-snow tires. Apparatus brakes must be in proper adjustment so that they do not grab and throw the vehicle into a skid or spin.
- Full chains — Full chains are generally put on for significant snowfall (six inches or more; Figure 2) or in the absence of automatic chains. Any chains in contact with the tires make it much harder to stop the apparatus, as there is less road surface area in contact with the tire.
