What is the maximum lane/alley speed, unless otherwise posted?

• A. 10km/h
• B. 15km/h
• C. 20km/h
• D. 25km/h

Answer: (C)

The maximum speed limit on a lane or alley, unless otherwise posted, is set at 20 km/h. This speed limit is established to ensure the safety of all road users, including pedestrians, cyclists, and vehicles. Since lanes and alleys are often narrower, with more potential for interactions between different types of traffic and obstacles, a lower speed helps to reduce the risk of accidents.

In residential areas or locations where people may frequently be present – such as children playing, parked vehicles, or pets – maintaining this speed limit allows drivers to react more effectively to sudden changes in their environment. Additionally, it encourages cautious driving behaviors that are essential in more confined spaces.

The other speed options are lower or higher than the designated limit. A speed of 10 km/h would be too slow for most vehicle operations, while 15 km/h might not provide an adequate flow of traffic. Speeds higher than 20 km/h would increase the risk of accidents and are not suitable for the intended context of lanes and alleys. Thus, the established maximum of 20 km/h balances safety with reasonable traffic flow.
