What is an important feature of dollies manufactured after 1998?

They have higher payload capacity

They are required to have a malfunction lamp on the left side

Dollies manufactured after 1998 are specifically required to be equipped with a malfunction lamp on the left side. This feature enhances safety by providing a visual alert to the driver about any issues with the dolly, particularly those that may affect the vehicle's operation or safety. The malfunction lamp serves as an important monitoring tool, as it can indicate problems such as electrical failures or issues with the braking system, ensuring that drivers are aware of potential hazards during operation.

While the other features listed may have their own benefits, they do not represent requirements that apply specifically to dollies manufactured after this date. The focus on safety features such as the malfunction lamp reflects industry standards aimed at improving driver awareness and reducing accidents on the road.
