There is a precise moment when the track disappears. The ground becomes lighter and softer, the vehicle feels heavier, the steering wheel becomes lighter, and the vehicle’s trajectory seems to take on a life of its own. That is when sand driving truly begins: a discipline that relies less on power than on observation and anticipation. Many travellers discover this transition during their first off-road expedition, and many are surprised by the same thing: in the sand, it is not brute force that gets you through, but finesse.
This article brings together the techniques and principles our instructors teach in the field, from the first tyre deflation to reading a road book. It is aimed at complete beginners as well as experienced drivers who want to structure and improve their practice. One thing should be made clear from the outset: nothing that follows can replace supervised, hands-on training. You do not become a skilled sand driver by reading about it; you become one by driving, under guidance, on terrain chosen specifically for that purpose.
The Fundamentals to Understand Before Driving on Sand
Before talking about dunes, it is important to talk about mechanics. A 4x4 is not simply a raised car; it is a vehicle with several transmission modes, and knowing which one to engage, when and why can make all the difference. Low range provides greater available torque and allows the driver to move forward with very precise throttle control. In the sand, this finesse is more valuable than any sudden burst of acceleration, because once a wheel starts spinning, it no longer pushes the vehicle forward—it starts digging underneath it.
Differential locks follow the same principle. They force the wheels on the same axle, or both axles, to rotate together, preventing a wheel with little or no traction from absorbing all the power. However, they are not a permanent off-road mode: when engaged at the wrong time, on hard ground or through a tight turn, they can put unnecessary strain on the drivetrain. Our instructors emphasise this point from the very first day: understanding what you are activating is just as important as knowing how to deactivate it.
Then comes the most important concept of all: momentum. In the sand, you do not stop moving to think; you maintain a steady motion that keeps the vehicle on the surface. The rule we repeat during training can be summed up in one sentence: as slow as possible, as fast as necessary. No unnecessary high revs and no sudden stops—just a carefully chosen pace that is maintained. That is exactly what our instructors, experts in the terrain, teach long before tackling the first dune.
Tyre Pressure: The First Key to Driving a 4x4 on Sand
If one single action could summarise sand driving, it would be this. Deflating your tyres is not simply a comfort trick—it changes the physics of how the vehicle interacts with the ground. A tyre with lower pressure flattens and lengthens, increasing its contact surface. The vehicle’s weight is then distributed over a much larger footprint, allowing the wheels to sink less and float more rather than digging into the sand. The same vehicle, in the same place, may either get through or become stuck depending on this single adjustment.
There is no universal pressure, which is precisely why you will not find a specific figure here. The right pressure depends on the vehicle, its load, the type of tyres and the nature of the sand. It should be determined on site, with an instructor, by observing how the vehicle behaves. What remains constant, however, are the precautions. At low pressure, sharp steering movements, high speeds and hard edges should be avoided, as the tyre may become damaged or come off the rim.
Reinflating the tyres is an integral part of the process; it is not an optional detail to be forgotten. As soon as you return to a rocky track or a paved road, the pressure should be increased again before picking up speed. On our road trip formats, these transitions are part of the rhythm of the day and are anticipated collectively rather than dealt with individually.
Crossing a Dune: Reading the Slope and Approaching It Straight On
A dune should be read before it is crossed. You stop, observe, and if necessary, walk up to discover what lies on the other side. This reconnaissance is never a waste of time—it is an essential part of the crossing. You assess the slope and its consistency, the colour of the sand, the presence of recent tracks and, above all, the shape of the crest.
The approach should always be made straight up the slope, never diagonally. Climbing a dune at an angle can cause the vehicle to drift sideways, transfer weight to the downhill wheels and create a risk of rollover. It is simply not something you should do. Acceleration should be progressive and anticipated. You build up the necessary momentum at the bottom, maintain it, and then ease off before reaching the crest—not after. The crest often hides a sharp drop or a leeward face that is much steeper than the side you climbed. Reaching it with too much speed can send the vehicle airborne without knowing where it will land.
Another absolute rule is never to begin a climb without a fallback strategy. If the vehicle loses momentum, do not insist. Stop in a straight line, reverse back down in your own tracks, staying aligned with the slope and avoiding sudden movements, then reassess the situation. Deciding not to cross a dune and choosing to go around it is not a failure—it is a driving decision. In the field, our instructors make this decision regularly, because safety always takes priority over the planned itinerary.
Reading the Terrain: Firm Sand, Soft Sand and Desert Traps
Sand is not a uniform surface. Firm sand, compacted by wind or moisture, can often be recognised by its darker colour, slightly crusted surface and the dull sound it makes underfoot. Soft sand tends to be lighter and finer; it collapses under your shoes and leaves a deep footprint. Walking a few metres before committing to a route remains one of the most reliable methods, and this habit is quickly developed.
Certain areas require particular vigilance. Fech-fech, an extremely fine powder that accumulates in depressions, can hide beneath a surface that appears solid: the vehicle can suddenly sink into it without warning. Wadis, meanwhile, are temporary riverbeds that can be pleasant to drive through but are capable of filling very quickly when a storm breaks far upstream, sometimes completely outside your field of vision. You should not camp in them or linger there when the weather begins to change.
La lumière fait partie intégrante de cette lecture. Au milieu de la journée, le soleil au zénith écrase les reliefs, les creux et les cassures disparaissent, et le terrain devient presque illisible. Tôt le matin et en fin d’après-midi, la lumière rasante redessine chaque ondulation, les ombres racontent le relief. Ce n’est pas un hasard si les journées de raid au Maroc, au Sénégal et en Mauritanie s’organisent autour de ces deux fenêtres.
Getting Stuck and Getting Out: A Normal Part of Sand Driving
Everyone gets stuck in the sand at some point. Beginners, experienced drivers and even instructors themselves. It is not an exceptional incident; it is simply part of the day, and learning to deal with it without stress is an important part of the experience. The most decisive reflex can be summed up in one sentence: as soon as the wheels start spinning, lift off the accelerator. Continuing to accelerate will never free the vehicle; it will simply dig four holes, cause the underbody to rest on the sand and turn a ten-minute stop into a long recovery operation.
The basic method always remains the same. Switch off the engine, get out and assess what is actually touching the ground: the wheels, but also the chassis, which may sometimes be resting on a ridge of sand left between the tracks. Then remove the sand in front of or behind each wheel, depending on the chosen direction of exit, create a gradual ramp, restore traction and move off again very gently—often by reversing into your own already-compacted tracks.
This is also where travelling in a convoy really comes into its own. One vehicle alone in the sand can become a problem. Two vehicles travelling together can become a solution. The distance between vehicles, the order in which they pass, keeping an eye on one another through the mirrors and communication between crews are all as much a part of off-road driving as steering itself. No one drives alone, and no one is left behind. It is this collective organisation that allows the journey to continue with confidence.
Navigation: Maps, Compass Bearings, Road Books and GPS
When tracks multiply and landmarks begin to disappear, navigation becomes a skill in its own right. It starts with the map: identifying directions, recognising terrain features, understanding scale and estimating your position before you even start driving. The compass complements this by providing a bearing—a direction to follow. Knowing how to maintain that bearing for several kilometres while navigating around obstacles without losing your line may seem simple on paper, but it becomes much more demanding in the field.
A road book follows a different logic, based on a sequence of boxes or diagrams. Each one combines a distance—both the distance covered from the starting point and the distance from the previous box—a navigation diagram representing a decision point, intersection, change of direction or specific section, and notes indicating a danger, visible landmark or instruction. You do not simply read a road book; you experience it in real time as a team, with one person driving and the other giving directions. This coordination is exactly what teams preparing for events such as the Rallye Aïcha des Gazelles or the Dakar Classic are looking for.
GPS has its place—but in the right place. It can confirm a position, record a route and provide reassurance when everything looks the same on the horizon. However, it cannot replace observation or reasoning. Batteries run out, and an incorrectly entered point can lead you far away from the planned route. A good navigator cross-checks different sources of information and keeps their eyes on the terrain.
