Vehicle tracking shots are among the most demanding sequences to prepare. The travelling car, the Russian arm, and the classic car mount each answer different situations — and choosing the wrong tool can compromise an entire shooting day. This guide covers all three systems, their operational logic, safety requirements, and real market budgets for 2025.
What is a travelling car and when should you use one?
A travelling car — also called a low loader or insert car depending on its configuration — is a specially adapted vehicle built to carry a camera and film another vehicle in motion. The actor drives (or simulates driving) their own vehicle, which is either placed on a platform or towed, while the camera shoots from the travelling car itself.
There are two main categories. The low loader (low platform) places the filmed vehicle on a lowered trailer, towed by a specialised truck. The camera frames the actor’s face through the windscreen or shoots the interior of the cockpit. The insert car is a standalone vehicle — usually a van or adapted 4x4 — onto which camera arms are mounted. It moves around the filmed vehicle rather than carrying it.
The low loader is essential whenever the director wants clean interior shots, free of road vibrations and without constraints for the actors. The actor does not have to drive at all: they can play their scene, their gaze directed toward a partner or a playback screen. It is the standard on HBO and Netflix productions for all in-car dialogue sequences.
How does the Russian arm work on a film shoot?
The Russian arm is a gyro-stabilised arm mounted on an all-terrain vehicle or truck. It films a moving vehicle from the outside, delivering wide-amplitude movements with electronic stabilisation that absorbs road irregularities.
The two dominant systems on the European market are the Filmotechnic Russian Arm and the Performance Filmcar. These rigs weigh several hundred kilograms and require a purpose-built carrier vehicle — typically an SUV or a rear-engine specialist vehicle for load-distribution reasons. The arm itself can reach 5 to 6 metres of extension, enabling angles that would otherwise be impossible.
“The Russian arm radically changes what you can do with a car shot. You go from a flat shot at window height to overhead angles, low angles, or movements that track the vehicle while sweeping through a curve. It gives the shot a life that no conventional car mount can replicate.”
The Russian arm operator works from the cab of the carrier vehicle via a remote-control system — typically a remote head of the Scorpio or Libra Head type. Coordination between the remote operator, the carrier vehicle driver, and the driver of the filmed vehicle is critical. A gap of a few metres is enough to lose the frame.
Technical limitations of the Russian arm
Gyroscopic stabilisation is impressive, but not infallible. On heavily undulating roads, cobblestones, or tracks, micro-vibrations persist in the image. The carrier vehicle’s speed is also a limiting factor: above 80–90 km/h, aerodynamic forces on the arm become significant and certain manufacturers impose maximum speeds for safety reasons.
Setup takes several hours. Gyro calibration, counterweight adjustment to match the camera, arm tests coordinated with the driver — all of this must be planned the day before or early on the morning of the shoot. Never under pressure.
What is a car mount and when is it sufficient?
The classic car mount covers any system for fixing a camera directly to a vehicle. High-grip suction cups (Kupo or Hague systems), window-clamped mounting bars, platforms bolted to the roof or bonnet.
It is the least expensive and fastest solution to install. It works perfectly for onboard shots: the driver’s point of view, the dashboard, the mirrors, or fixed exterior shots while the car is moving. Stabilisation is then provided by a lightweight gimbal (such as the DJI RS or MōVI) or a conventional fluid head.
Its main drawback is the constraint it places on actors: with a camera fixed to the passenger window, the performance space is reduced, microphone cables can interfere, and road vibrations transmit to the image if vehicle preparation has been neglected (suspension bleed, shock absorber check).
On long-format productions, Fabrice Mignot regularly combines all three approaches depending on the shot: car mount for quick cutaways, insert car for dialogue scenes, Russian arm for dynamic exterior shots of the vehicle.
Safety and coordination: stunt drivers, police, road closures
Vehicle machinery sequences are the most tightly regulated legally and the most operationally demanding. Three areas require particular preparation.
Coordination with stunt drivers
On a shoot involving a low loader or Russian arm, the driver of the tractor or carrier vehicle is always a professional stunt driver holding a professional card issued by the National Joint Employment Commission for the Film Industries (CPNEISC). This is not a regular driver: low-speed manoeuvres with a loaded platform, three-point turns in restricted spaces, or coordination with the filmed vehicle all require specific expertise.
The Key Grip coordinates directly with the stunt coordinator to define speeds, trajectories, and safety margins. These discussions happen during location scouting and in prep meetings — never on set at the last minute.
Prefectural authorisation and road closure
Whenever a shoot involves moving vehicles on a public road, a prefectural authorisation is mandatory. Processing times range from 10 to 30 days depending on the prefecture. The application includes the traffic plan, intervention times and zones, and the list of specialist vehicles.
For road closures, the national police or gendarmerie provides an escort, the cost of which falls on the production. On a complex travelling car sequence, the police escort budget can represent several thousand euros over two to three days.
Securing the mobile set
Technicians working on a moving low loader wear harnesses and anchor lanyards. Onboard camera operators are strapped in. These safety items are never optional, regardless of the speed of travel.
Budget and logistics: real costs of a complete travelling car unit
The rates below reflect market prices in France in 2025, for high-end equipment with professional drivers.
| Equipment | Indicative daily rate |
|---|---|
| Insert car (vehicle + safety driver) | €1,500 – €2,500 |
| Full low loader (tractor + platform + stunt driver) | €3,000 – €5,000 |
| Russian arm (vehicle + operator + remote head) | €4,000 – €8,000 |
| Car mount with suction cups (rental only, no driver) | €300 – €600 |
| Complete package (Russian arm + insert car + escort) | €6,000 – €12,000 |
These rates exclude travel from the equipment base, fuel, and authorisation costs. On a Paris-region shoot with a road closure, the total budget for a day of vehicle shots can exceed €15,000 when all line items are included.
Advance logistics are as critical as the equipment itself. Transporting a low loader requires a heavy-equipment truck, routes verified for height and width clearance, and appropriate parking areas at the shoot location. These constraints must be anticipated during location scouting — not the night before the first day of shooting.
Fabrice Mignot’s field expertise
Thirty years of professional sets, from Agat Films productions to HBO series and Prime Video — Fabrice Mignot has supervised hundreds of vehicle sequences, from a simple in-car dialogue scene to a night-exterior long take with a Russian arm.
“The difference between a good day of vehicle shots and a bad one is preparation three days out. Has the low loader been checked? Does the stunt driver know the trajectory? Has the prefecture confirmed? If one of those boxes isn’t ticked the night before, the day will be difficult.”
His contribution goes well beyond equipment management. He coordinates between the safety teams, the specialist suppliers, and the camera crew — a pivotal role that often determines whether a difficult sequence makes its schedule or doesn’t.
For productions new to vehicle machinery, his standing advice is to budget a technical prep day for all systems before the first shooting day. The cost of that day is marginal against the risk of losing a full production day because arms and configurations were never tested.

FAQ
What is the difference between a low loader and an insert car?
A low loader is a lowered trailer towed by a specialised truck, on which the actor’s vehicle is physically placed. An insert car is a standalone vehicle that moves around the filmed vehicle. The low loader is preferred for interior shots with actors; the insert car for dynamic exterior shots.
Is a special permit required to shoot with a Russian arm on a public road?
Yes. Any shoot involving specialist moving vehicles on a public road requires a prefectural authorisation, generally processed within 10 to 30 days depending on the prefecture. The production must also budget for police or gendarmerie escort costs, which are charged to the production.
What budget should be planned for a day of vehicle shots with a Russian arm?
A complete Russian arm unit (carrier vehicle, operator, remote head) costs between €4,000 and €8,000 per day. With an insert car in addition and escort costs on an open road, the total budget for a day of vehicle shots can reach €10,000 to €15,000.
Can a standard car mount replace a Russian arm?
No. The car mount suits fixed onboard shots or light cutaways, but it cannot deliver the wide-amplitude movements (overhead angle, rotation around the vehicle, arm acceleration) that the Russian arm provides. They are two complementary tools, not interchangeable ones.
How long does it take to set up a Russian arm before a shoot?
Installing and calibrating a Russian arm typically takes 2 to 4 hours — gyroscopic calibration, counterweight adjustment to match the camera, arm tests coordinated with the driver. This time must be budgeted into the schedule and cannot be compressed without risk to quality and safety.
