What is the proper way to approach a roundabout?

Yielding to traffic already in the roundabout is the proper way to approach a roundabout. This procedure allows for a smooth flow of traffic and ensures safety. Vehicles already in the roundabout have the right of way, which helps prevent accidents and congested traffic. By yielding, a driver can assess the gaps in traffic and make informed decisions about when to enter, thereby maintaining the efficiency of the roundabout system.

The other choices involve unsafe practices. Speeding up to beat other vehicles can lead to reckless driving and increase the risk of collisions. Entering the roundabout immediately without ensuring it's clear could lead to dangerous situations if there are vehicles present. Ignoring signage disregards the rules of traffic management, which are designed to promote safe and orderly driving.
