Final answer:
The Slow-Moving Vehicle sign tells you to keep in the right-hand lane when driving slow.
Step-by-step explanation:
The sign that tells you to keep in the right-hand lane when driving slowly is the Slow-Moving Vehicle sign. This sign is a reflective orange triangle with a red border. It is typically used to indicate a vehicle or equipment that is moving at a much slower speed compared to the normal flow of traffic. Slow-moving vehicles are required to keep to the right to allow faster-moving vehicles to pass safely.
For example, agricultural vehicles, such as tractors or combines, often display this sign to alert other drivers that they are traveling at a slow speed. The purpose of this sign is to enhance visibility and promote safe driving practices.
It is important to note that the Slow-Moving Vehicle sign is not specific to the right-hand lane. It is a general indication to drive slowly and allow others to pass. However, if you are driving slowly in the right-hand lane, this sign serves as a reminder to stay in that lane and allow faster traffic to pass on the left.
