Final answer:
You should park no more than 18 inches from the curb when parking on the side of the road. This standard distance is accepted in many places for safety and traffic flow reasons, but always verify with local laws.
Step-by-step explanation:
When parking on the side of the road, you should be no more than 18 inches from the curb. The exact distance may vary depending on local laws, but it is commonly accepted that no more than 1.5 feet from the curb is a reasonable distance to ensure safety and to avoid obstructing traffic.
Parking too far from the curb can cause dangers to both pedestrians and other vehicles, possibly leading to traffic violations. To visualize this distance, think of it being roughly half the length of a standard adult's bicycle. Always check your local regulations for the most accurate and lawful guidance on parking distances.
