This exam question from the Traffic Rules of Ukraine concerns road safety in traffic flow and the prevention of rear-end collisions. It tests the understanding of a simple but critically important pattern: as speed increases, a vehicle covers more meters during the driver's reaction time, and the braking distance becomes longer, so more space is needed to stop. That is why the correct choice of distance directly affects the safety of maneuvers and the ability to avoid collisions.
In terms of content, this question belongs to the topic "Positioning of vehicles on the road, distance and interval" and is based on clause 13.1 of the Traffic Rules, which directly states the driver's obligation to maintain a safe distance depending on speed, road conditions, vehicle condition, and other factors. The definition of the term "distance" from clause 1.10 is also used, as the longitudinal distance between vehicles, and the general logic of safe driving is consistent with the requirements of clause 12.1 regarding the choice of a driving mode that allows constant control of the vehicle.
The analysis of the answer options in this theoretical exam task is straightforward: the statement about the need to increase the distance as speed increases is correct, because both the decision-making time and the braking distance "cost" more meters at high speed. Denying this statement contradicts the Traffic Rules of Ukraine and the real physics of movement: a distance that is sufficient at 50 km/h may become dangerously short at 90–110 km/h. In practice, it is useful to rely on the two-second rule (and increase it in poor conditions) or the approximate "meter rule," where on a dry road a safe distance is often estimated as about half the speed in meters.
Clause 13.1
The driver, depending on the speed of movement, road conditions, characteristics of the cargo being transported, and the condition of the vehicle, must maintain a safe distance and a safe interval.
Brief explanation of application: this clause directly establishes the dependence of a safe distance on speed — as speed increases, the driver must choose (and maintain) a greater distance to the vehicle ahead.
Clause 1.10 (term "Distance")
Distance — the longitudinal distance between moving vehicles.
Brief explanation of application: the question concerns specifically the "distance" as defined in the Traffic Rules — the longitudinal gap between cars in the flow.
Clause 12.1
When choosing a safe speed within the established limits, the driver must take into account the road conditions, as well as the characteristics of the cargo being transported and the condition of the vehicle, in order to be able to constantly control its movement and drive it safely.
Brief explanation of application: higher speed complicates control and safe driving, so the driver is obliged to coordinate speed and driving mode with the conditions, in particular by ensuring a sufficient distance.
That is, the correct answer is "Yes.", given that according to the definition in the Traffic Rules, the driver is obliged to maintain a safe distance, which directly depends on the speed (clause 13.1).
While driving, the driver is required to choose a safe distance to the vehicle ahead in order to be able to avoid a collision in case of its sudden braking or stopping. This distance is not set by a single fixed number, because it depends on driving conditions, but the logic is always the same: the faster you drive, the more space you need to stop.
At higher speeds, the car covers a greater distance in the same amount of time, and the braking distance also increases. Even if the driver reacts quickly, during the reaction time the vehicle manages to travel more meters than at a lower speed. Therefore, the distance that was sufficient at 50 km/h becomes insufficient at 90–110 km/h.
For practical assessment of distance, the “two-second rule” is often used: choose a stationary landmark on the road (a post, sign, or marking) and make sure your car passes it no sooner than about two seconds after the car ahead. If speed increases or conditions worsen (wet or slippery surface, poor visibility), this pause may no longer be enough and should be increased.
You can also use the “meter rule of thumb”: on a dry road, a safe distance is often taken as approximately half the speed (in meters). For example, at 110 km/h this will be about 55 meters; at lower speeds a shorter distance is needed, and at higher speeds—a longer one.
Therefore, the correct answer is "Yes," because as speed increases, the distance traveled during reaction time and the braking distance increase, so to avoid a collision, you need to increase the distance to the vehicle ahead.
