There are at the moment two kinds of roundabouts in Hong Kong. We name them typical roundabouts and new spiral roundabouts. Probationary (P-license) drivers are at all times confused by them since every has its personal guidelines for giving indicators and precedence. However passing the driving take a look at doesn’t routinely make you an knowledgeable, as solely the Yau Tong take a look at route has a roundabout.
What’s extra, there is no such thing as a clear consensus as to the best way to use roundabouts. Some drivers are likely to drive alongside the outer lane it doesn’t matter what, inflicting site visitors congestion. Some drivers even overtake by altering to the mistaken lane, leading to automobile accidents. These atrocities have left a status of “black spots” on some roundabouts!
Kwiksure presents the similarities and variations between the traditional roundabouts and spiral roundabouts, in addition to a situation evaluation.
Similarities and variations between the traditional roundabouts and the spiral roundabouts
Earlier than coming into a roundabout, you will notice a triangular “roundabout forward” signal about 100 meters prematurely. It’s often arrange alongside the pedestrian route. At about 50 meters earlier than the roundabout, you will notice an enormous blue route signal.
Guidelines of use

Resolve as early as attainable which exit you need to take and swap to the right lane.

Typical roundabouts vs. spiral roundabouts: Driving suggestions
The Transport Division launched a guide named “How A lot You Know About Guidelines of Utilizing Roundabouts”, by which we are able to see that the 2 kinds of roundabouts are usually not too dissimilar in the case of utilization.
If you’re in the end making a left flip (i.e. taking the exit on the left), journey alongside the outer lane and preserve left.
If you’re in the end making a proper flip or taking different exits (i.e. taking the exit on the precise), journey alongside the interior lane and preserve proper.

Typical roundabouts vs. spiral roundabouts: The “give-way precedence” controversy
If the principles of use are so clear, why do site visitors accidents nonetheless occur every so often? The wrongdoer is the precedence situation on the exits.
Within the typical roundabout, autos on the interior lane ought to give technique to autos on the outer lane to depart first. Conversely, within the spiral roundabout, autos on the outer lane ought to give technique to autos on the interior lane to depart first. Previous or new, bear in mind this rule of thumb in the case of roundabouts: look proper when coming into and look left when exiting in case any car crosses your path from behind on the left. Additionally, be careful for lengthy autos (e.g. container vehicles) as they might additionally cross your path after they enter and exit the roundabout.
The emergence of spiral roundabouts stems from an commentary that drivers exiting a standard roundabout would make a number of lane adjustments without delay, growing the danger of accidents. Due to this fact, in 2004, the Transport Division rolled out spiral roundabouts on a trial foundation. But out of the 327 roundabouts in Hong Kong, there are solely 23 spiral ones – accounting for a mere 7% of the full. The coexistence of each roundabouts, in addition to the distinction between give-way guidelines, has continuously prompted accidents.
