The C37 sign means you cannot park on the side of the road where the sign is displayed on any calendar day with an even number (e.g., the 2nd, 14th, 28th). You must check the calendar date and park on the side that is permitted for that day.
The prohibition begins at the sign and typically extends to the next intersection or until another sign indicates otherwise. Crucially, the restriction depends on the calendar date; it applies specifically on even-numbered days on the marked side of the road.
A common mistake is assuming parking rules are the same every day. Learners might forget to check the calendar date or fail to realise the ban only applies on even-numbered days. Some might also park on the even-numbered side and leave their car overnight, only to find it's an even date the next day.
Yes, the C37 sign specifically prohibits parking on even-numbered days. On odd-numbered days, parking is generally permitted on the side where the sign is displayed, provided no other signs or regulations prevent it. Always look for other signs that might modify parking rules.
If you park on the C37 side on an even-numbered day, and your vehicle remains there as the date rolls over to an odd-numbered day, you will typically be permitted to stay parked. The restriction applies only to parking initiation and presence during the even-numbered day period. However, you must ensure you move your vehicle if it becomes an even-numbered day again.
While the sign itself indicates a general ban on even days, look out for additional plates below the C37 sign. These might specify exact hours when the ban is active, or provide exceptions for residents with permits or for delivery vehicles during certain times.
