DRIVER AND SPOTTER: THE TWO PERSON SYSTEM

13 min · Full library · written from fifteen years in the terrain

The point

After this lesson you can operate as half of a disciplined two person driving team, with clear authority, an agreed signal set and a debrief habit, and apply it directly to family and group touring.

The Technique

  1. The two person system exists because a driver cannot see the ground under their vehicle, cannot see the underbody clearances, cannot judge the vehicle's angle accurately from inside it, and is simultaneously running the machine. That is too many jobs. Splitting them is not a courtesy or a sign of inexperience, it is how competent crews operate, and the highest level competitors use it on every obstacle without exception. The division is simple and it must be explicit: the driver owns the vehicle's inputs, throttle, brake, gear, steering and the decision to commit. The spotter owns the information, the line, the clearances and the stop. Neither does the other's job. A spotter who starts second-guessing throttle is out of their lane, and a driver who starts choosing their own line mid-obstacle has just made the spotter useless and dangerous.
  2. The stop call is the foundation and it must be absolute. Any person, driver, spotter or bystander, can call stop, and the vehicle stops immediately with no argument, no interpretation, and no completing the current movement first. This works only if you never punish a stop call. If someone stops the attempt and it turns out they were wrong, the response is thanks, we reset, not an eye roll. The moment a stop call carries a social cost, people hesitate, and hesitation is exactly the failure you built the system to prevent. Competitors treat this as a rule rather than a courtesy, and remote touring groups should too, because the person who sees the sliding rock or the wheel about to drop off a shelf is often not the driver.

These sports kill people. Not rarely, and not only the reckless - every season they kill riders who were experienced, fit, well equipped and doing everything properly. That is the honest starting position and everything else we do sits on top of it.

The mountain does not know who you are. Snow releases on people with twenty years in it. Machines roll on riders who have done that line a hundred times. Water, rock, trees and other people are indifferent to how good you have become. Every time you go out you are accepting a real chance that it goes wrong, and no amount of skill removes that chance - it only changes the odds.

What that looks like in these disciplines, plainly: avalanche burial and asphyxiation, being crushed under a machine, head and spinal injuries from falls and impacts, drowning, hypothermia, and collisions with trees, rocks and other riders.

We work in remote country, so distance is part of it. A serious injury usually means hours before a helicopter can reach you, and weather sometimes means no helicopter at all. Help being close is not a feature of any trip we run.

This is exactly why we prepare the way we do. Training before you ride, gear standards, minimum party sizes, people who know the ground, and a willingness to call a day off. All of it is about improving your odds and making the group capable of looking after itself. None of it makes anything safe, none of it makes anyone competent, and passing our training is not a qualification. Anybody who tells you they can make this safe is selling something.

Everyone out there is relying on everyone else having been honest about what they can actually do. If reading this has made you hesitate, that is worth listening to rather than talking yourself out of.
