Saskatchewan SGI Driving Practice Test

A sign with a picture of a person holding a flag belongs to the traffic control signs category. This type of sign indicates that there is a traffic control person present on the road ahead. This person is usually a construction worker or a school crossing guard, and their presence can alert drivers to potential changes in traffic flow or the need to slow down and proceed with caution. Option A is incorrect because construction zones would typically have orange warning signs, not traffic control signs. Option B is incorrect because school zones use different signage to indicate their presence, such as a school zone sign or a speed limit sign. Option D is incorrect because it does not involve the use of a person holding a flag and is not specific to any particular type of crossing situation.
