What type of driving behaviour could require a physical coordination test?

Driving when suspected to be impaired by drugs may require a physical coordination test because law enforcement needs to assess the driver's ability to perform critical tasks required for safe driving. Impairment from drugs can significantly affect a person's motor skills, coordination, and judgment, which are essential for operating a vehicle safely.

When officers suspect a driver may be under the influence of drugs, they may conduct field sobriety tests, which are designed to evaluate cognitive and physical abilities. These tests often include tasks such as walking in a straight line, balancing, or following an object with their eyes. The results help determine if the driver is fit to drive or if further action, such as an arrest for impaired driving, is warranted.

In contrast, the other scenarios listed do not typically present the same concerns about impairment or the need for coordination assessments. For example, driving during the day, wearing glasses, or driving on highways do not inherently indicate a diminished capacity to operate a vehicle safely.
