Moose on the Trans-Canada at Last Light
At 6:40 p.m. on a cold, flat-grey late-September evening you are westbound on the Trans-Canada Highway near Terra Nova. The posted limit is 100 km/h and your speedometer reads 105 km/h. You switched your headlights on twenty minutes ago. A compact car is following about 15 metres behind - close enough that its headlights fill your mirrors. The pavement is damp and the outside temperature display reads 3 °C.
About 120 metres ahead, on the right shoulder, a dark shape resolves into a moose standing side-on, facing the highway. Beyond it, in the ditch grass, something else is moving. A transport truck is approaching in the oncoming lane about 300 metres away, marker lights on.
Your car is a 2016 mid-size sedan with winter tires, ABS and electronic stability control. You are carrying two adults and a full trunk.
1. Set out your actions over the next three seconds and explain why braking is preferred to swerving.

At 105 km/h you cover roughly 29 metres every second, so 120 metres is about four seconds of travel - barely enough to react and shed speed. The sequence is: firm, progressive pressure on the brake pedal, both hands on the wheel, eyes on the gap you intend to use, no steering input unless the moose actually moves into your lane.
Why not swerve: a violent lane change at 105 km/h on damp pavement, with a 300-metre oncoming truck, trades a survivable frontal impact for a possible head-on, rollover, or ditch strike. Stability control helps but does not repeal physics - it cannot create grip that the damp surface does not have. Braking keeps you in your lane, keeps ABS and stability control working in their designed envelope, and bleeds speed, which is what determines how much energy reaches the passenger compartment.
If the moose does step into the lane, the priority becomes passing behind it rather than in front of it, and braking hard at the last moment is better than a glancing high-speed swerve. A full trunk and two passengers also lengthen your stopping distance, so start braking the moment you identify the hazard, not when you are certain.
2. The car behind is 15 metres back. What following distance should it have had, and how does its position change what you do?
Read the worked answer
Using the four-second rule, a following vehicle at 105 km/h needs about 117 metres - roughly 29 metres per second times four - and more than that on a damp surface at dusk when a moose can appear without warning. At 15 metres it has less than one second of gap, is likely to rear-end you whatever you do, and is also blinding you through the mirrors.
That changes your braking style, not your decision to brake. You brake firmly but progressively rather than stamping on the pedal, so your brake lights come on early and stay on, giving the driver behind the longest possible warning. You do not brake late and hard unless the moose is already in your lane, in which case the collision ahead is the greater threat and you accept the risk from behind.
You also leave yourself an exit. If the car behind is clearly not reacting, the shoulder or the gravel is a better place to be than a rear-end at highway speed, so check your right side before you need it. Resist the urge to accelerate away from the tailgater; that only raises the speed at which everything happens.
3. How do you manage headlights and the oncoming truck, and what do you do after you pass the moose?
Read the worked answer
Keep low beams. High beams at 300 metres would dazzle the truck driver, whose vehicle will reach you in a few seconds, and glare also makes your own lane harder to read. Do not flash the truck - it is not a signal to warn about the moose and it will only blind someone who is about to pass you. Avoid looking at the truck's lights; steer by the right edge line and the shoulder.
At 3 °C and damp, bridge decks and shaded sections may be at or below freezing, so your braking and steering inputs should stay smooth. The second shape moving in the ditch means the first moose is not the whole hazard: slow further, scan the whole right shoulder, and expect the animal to turn and follow the road.
Once past, do not immediately resume 105 km/h. Hold a reduced speed for a few hundred metres, use the mirrors to check the tailgater has not tried something worse, and if the car behind stays glued to your bumper, pull off at a safe turnout and let it go.
