Crew Modes
Configure the number of drivers for a mission — single driver, double crew, and relay driver — and understand how each mode affects dispatch and RSE compliance.
Overview
Crew modes (screen G-05) define how many drivers are associated with a single mission. The standard mode is Single driver — one driver for the entire trip. For missions where legal driving time limits, RSE compliance rules, or logistical requirements necessitate additional staffing, two alternative modes are available: Double crew and Relay driver.
The crew mode is selected at the time of dispatch, before or during the assignment step. Once a mission is in progress, changing the crew mode requires cancelling and reissuing the assignment.
Single driver
Single driver is the default mode. One driver is responsible for the entire mission from pickup to drop-off.
- The dispatch engine searches for one available driver matching the availability window
[pickupAt, estimatedEndAt], vehicle category, and RSE compliance. - All push notifications, mission briefing, and status updates go to that single driver.
- Billing is tied to the original quote with no split.
Use single driver for standard TRANSFER, EXCURSION, and DISPO missions within normal driving time limits.
Double crew
Double crew assigns two drivers to the same vehicle and mission. Both drivers are present for the entire trip; one acts as the primary driver while the second provides mandatory rest compliance.
This mode is typically required when:
- The mission duration exceeds the maximum continuous driving time allowed under French VTC regulations.
- Your organization's
OrganizationLicenseRuleconfiguration mandates double crew above a certain trip duration threshold.
Dispatch behavior with double crew
When you select double crew, the assignment wizard (G-06) asks you to select two drivers rather than one. Both must:
- Be available for the full
[pickupAt, estimatedEndAt]window. - Hold a compatible licence and vehicle category.
- Pass RSE compliance checks individually.
Both drivers receive identical mission briefings and push notifications. The Gantt view shows both driver rows blocked for the mission duration.
Relay driver
Relay driver assigns two drivers who share a single vehicle sequentially — driver 1 covers the first leg, driver 2 takes over at a predefined relay point mid-route.
This mode is used for long-distance missions (e.g., Paris → Lyon) where a single driver would exceed rest time thresholds but the mission itself does not require two people to be present simultaneously.
How relay handoff works
- At dispatch, you specify the relay point (location and estimated handoff time).
- Driver 1 is assigned from
pickupAtto the relay handoff time. - Driver 2 is assigned from the handoff time to
estimatedEndAt. - Each driver sees only their own leg in the mobile app.
- The Gantt view shows driver 1's block ending at the relay point and driver 2's block starting there.
Availability check for relay
Each driver's availability is checked against their respective leg only:
- Driver 1:
[pickupAt, relayHandoffAt] - Driver 2:
[relayHandoffAt, estimatedEndAt]
This allows a driver who has an earlier mission ending before the relay point to serve as driver 2.
Selecting the crew mode
Crew mode is selected in the dispatch modal:
- Open the Dispatch mode modal (G-07) for the mission.
- Choose Assign directly or Broadcast.
- In the assignment configuration, select the crew mode from the Crew dropdown: Single, Double, or Relay.
- Proceed with the assignment wizard or broadcast configuration accordingly.
The system will automatically suggest an alternative crew mode if RSE compliance blocks the currently selected mode (see RSE Compliance).
Effect on the dispatch algorithm
| Mode | Drivers searched | Availability window checked |
|---|---|---|
| Single driver | 1 | [pickupAt, estimatedEndAt] |
| Double crew | 2 simultaneous | [pickupAt, estimatedEndAt] for both |
| Relay driver | 1 + 1 sequential | Leg 1 + Leg 2 intervals separately |

Broadcast Pipeline
Send a mission offer to multiple eligible drivers simultaneously — dispatch mode choice, broadcast tracking, driver proposals, and the anti-duplicate safeguard (FR395).
Direct Assignment
Assign a specific driver to a mission — the assignment wizard, eligible driver list, compatibility scoring, and the optimistic lock safeguard (FR394).
