True or False: Vehicles in a lane marked by "Lane Use Control" must turn in the direction of the arrow, regardless of the driver's wishes.

The assertion is true because "Lane Use Control" markings, including arrows, are designed to indicate the specific requirements for the use of that lane. When a lane is marked with a directional arrow, it communicates that all vehicles in that lane must comply with the direction indicated. This rule is crucial for maintaining safe and orderly traffic flow, as it prevents confusion and potential accidents that could arise if drivers were allowed to disregard these markers based on personal preference.

Regardless of a driver's wishes or the circumstances, such as the presence of other vehicles or safety concerns, adherence to lane markings is mandatory. This regulation ensures that all drivers are aware of and follow the same traffic rules, which contributes to overall road safety.
