Final answer:
In both the United States and Canada, drivers must use the right side of the road. Road signs in these countries are designed to conform to this standard, with some regions like Ottawa featuring bilingual signage due to historical settlement patterns.
Step-by-step explanation:
In the United States and Canada, you drive on the right side of the road. This standard is consistent across both countries, providing a uniform driving experience for travelers crossing the border between these neighboring nations. Understanding road signage is crucial when driving, and though some signs are universal, it's always important to interpret them correctly within the context of the local driving laws.
For instance, if you see a Stop sign in Ottawa, Ontario, you would need to recognize that it might be bilingual due to the historical presence of French and English settlers. This bilingual heritage is a result of historical divisions made by the British Parliament in 1791, splitting Quebec into Upper and Lower Canada, which led to the formation of English-speaking Ontario and French-speaking Quebec. Such regional differences can sometimes influence road signage, but the side of the road you drive on remains constant.
