When can lane closures be used on Virginia highways?

Lane closures on Virginia highways are permitted when they are necessary for construction or maintenance work, provided that proper guidelines and safety protocols are followed. This ensures that the closures serve a valid purpose, such as enhancing road safety, facilitating necessary repairs, or improving the overall infrastructure.

It's essential that these activities are conducted in compliance with specific regulations to minimize disruption to traffic flow and ensure the safety of both the workers and the traveling public. Proper management involves using appropriate signage, implementing traffic control measures, and coordinating with relevant authorities to communicate closures effectively.

Other scenarios mentioned in the choices, such as nighttime closures, holiday weekends, or times of low traffic volume, do not inherently justify lane closures if they are not linked to construction or maintenance activities. The focus on necessity and adherence to guidelines in the correct answer highlights the importance of balancing work needs with public safety and traffic efficiency.
