You already know that a red octagon means stop and a triangle means yield. But driving in New Jersey requires mastering a more specific set of rules. The state has its own regulatory signs that go beyond the basics, dictating precise actions at intersections, on highways, and in special zones. Understanding these nuances is key to driving safely and avoiding penalties on your license.

Intersections are where most traffic conflicts occur, and New Jersey has specific signs to manage them. While a right turn on red after a full stop is usually permitted, always look for signs that modify this rule. A 'No Turn on Red' sign is absolute. However, you will often see conditional versions. Some signs might prohibit the turn only during specific hours, like morning and evening rush hours, to protect pedestrians or manage heavy traffic flow. Ignoring one of these signs can result in a fine and, importantly, two points on your license.

Another critical sign is 'Left Turn Yield on Green'. This sign appears at intersections with a solid green light, not a green arrow. It means you are permitted to turn left, but only after yielding to all oncoming traffic. The drivers going straight have the right-of-way. You must wait for a safe gap in traffic before making your turn. Misjudging the gap is a common cause of serious accidents.

Once you're moving, you need to understand the rules for passing. A 'Do Not Pass' sign is a strict legal command. It's used in areas with limited visibility, like hills and curves, where passing could lead to a head-on collision. On the other hand, a 'Pass With Care' sign indicates that passing is allowed, but you should still be cautious. This sign is a reminder to ensure the way is clear before you attempt to overtake another vehicle. The lines on the road will always reinforce these signs: a solid line means no passing, while a dashed line means passing is permitted.

New Jersey also restricts road access based on vehicle size and weight. You might see signs that say 'No Trucks' or show a truck symbol with a weight limit, such as 'Over 4 Tons'. These restrictions are common on smaller roads and parkways not designed for heavy vehicles. These limits refer to the Gross Vehicle Weight Rating (GVWR), which is the maximum operating weight of a vehicle as specified by the manufacturer. It's crucial for commercial drivers to know their vehicle's GVWR and obey these signs.

Highways like the NJ Turnpike and Garden State Parkway have their own specific sign systems. One of the most critical combinations is 'Do Not Enter' and 'Wrong Way'. The 'Do Not Enter' sign, a red circle with a white horizontal bar, is typically posted at the beginning of a one-way street or ramp you should not enter. If you mistakenly pass this sign, you will shortly see a red rectangular 'Wrong Way' sign. This is your urgent final warning that you are driving against the flow of traffic and are in immediate danger of a collision. You must pull over and turn around as soon as it is safely possible.

New Jersey also uses High-Occupancy Vehicle (HOV) lanes to encourage carpooling and reduce congestion. These lanes are marked with a white diamond symbol painted on the pavement and on regulatory signs. The signs will specify the rules, such as the minimum number of occupants required (e.g., '2 OR MORE PERSONS PER VEHICLE') and the hours or days the restriction is in effect. Using an HOV lane without meeting the requirements can lead to a significant fine.

Now, let's see how well you know New Jersey's specific regulatory signs.

Mastering these specific signs is a big step toward becoming a safe and confident driver in New Jersey. Always stay alert and read every sign carefully.
