Taskr.DrivingRest 0.1.0

Taskr.DrivingRest

Taskr.DrivingRest is a lightweight .NET library that validates driver activity logs against core EU driving and rest-time constraints (Regulation (EC) No 561/2006).

It is designed for:

• fleet compliance checks
• tachograph ingestion pipelines
• simulation and rule-testing workflows

Highlights

• Stateless validator API
• Deterministic violation codes and windows
• Input contract checks (ordering, overlap, duration)
• Unit-tested rule behavior (13 tests currently)

Quick Start

using Taskr.DrivingRest;

var dayStart = new DateTime(2026, 1, 5, 0, 0, 0);

var log = new DriverActivityLog
{
    DriverId = "driver-42",
    Activities =
    [
        new()
        {
            Type = DriverActivityType.Rest,
            Start = dayStart,
            End = dayStart.AddHours(11)
        },
        new()
        {
            Type = DriverActivityType.Driving,
            Start = dayStart.AddHours(11),
            End = dayStart.AddHours(15.5)
        },
        new()
        {
            Type = DriverActivityType.Break,
            Start = dayStart.AddHours(15.5),
            End = dayStart.AddHours(16.25)
        },
        new()
        {
            Type = DriverActivityType.Driving,
            Start = dayStart.AddHours(16.25),
            End = dayStart.AddHours(18.5)
        },
    ]
};

var violations = DrivingRestValidator.Validate(log);
foreach (var v in violations)
    Console.WriteLine($"{v.Code} ({v.Article}): {v.Description}");
