Öxi in the Dark: Tyres, Wind and a Decision to Turn Back
Late November, 15:20, and the daylight is already going. You are in a two-wheel-drive estate car at the foot of Route 939 (Öxi) on the east side, heading towards Eskifjörður. The sign at the junction says 80 km/h, but the last 300 m is packed snow over ice, and the forecast is 18 m/s wind with drifting snow on the exposed summit. Outside temperature is -2 °C. The car has all-season tyres: fronts at 3 mm, rears at 5 mm, no chains, half a tank of fuel. Your partner and a 10-year-old are in the back; your phone is at 60 % and you have had no coverage for the last 20 minutes. The coast road round Route 1 is 40 km longer but stays near sea level. Another car has just pulled up behind you and the driver flashes the headlights, clearly intending to follow you up.
1. Assess the car's tyres and equipment against what this road and weather demand. What is legal, what is adequate, and what would you change?

The legal minimum in Iceland is 1.6 mm of tread, so 3 mm at the front is legal - but legality is the wrong test here. On packed snow and ice what matters is the rubber compound and the tread pattern: a summer-biased all-season tyre at 3 mm has lost most of its sipes and will slide on the hairpins. Having less grip at the front than the rear (3 mm against 5 mm) on a front-wheel-drive car also makes the rear more likely to step out under braking on a bend. Studded tyres are permitted from 1 November to 15 April, so late November is inside the window, and proper winter tyres without studs would also be a large improvement. Chains are not required by law and are impractical here, but a shovel, a warm blanket and a full tank are the working minimum. Half a tank on a pass with no services is marginal - fill up before the junction, not after.
2. The driver behind flashes you to go. Explain your decision and the factors that decide it.

Decline, turn round and take Route 1, and wave the following car past. The decision turns on the margin you have left, not on your confidence. Sunset is around 16:00, so you would cross the summit in the dark; 18 m/s on an exposed pass with a light two-wheel-drive car on worn all-season tyres is enough to push the car sideways on ice; and with no phone coverage, any incident becomes a wait in the cold for a 10-year-old. Against that, there is a lower, safer alternative that costs 40 km. The flashing headlights change nothing - another driver's impatience is not information about the road surface. Before choosing any mountain route in winter, check road.is and the Vegagerðin information line (1777) for closures; passes like this are shut at short notice. Turning back costs an hour. Continuing badly costs much more.
3. If you did go over, how would you drive the descent?
Read the worked answer
Drive for grip, not for schedule. Select a low gear before the descent and let engine braking hold the speed, so you touch the brakes only lightly and briefly - continuous braking on a long icy descent overheats them and can lock a wheel. Cruise control off. Make every input slow and small: the tyres have very little reserve, and a sudden correction is what puts a car into a slide. Leave four to five seconds to the car in front rather than the usual three, and hold well to the right on blind crests and bends where an oncoming vehicle may be straddling the centre line. Dipped headlights on. If the car starts to slide, ease off the accelerator and steer where you want to go instead of stamping on the brake. Watch for drifting snow and for the road narrowing where the plough has not been through.
