The most frequent (and most dangerous) mistakes
Certain behaviors recur regularly and really deserve to be discussed amongst ourselves:
– Assuming the wider road has priority — incorrect, without a sign. – Accelerating to “cut in line” — risky and potentially responsible in case of an accident. – Looking only in one direction — insufficient when several vehicles are approaching simultaneously. – Ignoring the simultaneous arrival of other drivers — a very common source of misunderstandings.
These behaviors are not insignificant. In the event of an accident, liability is assessed in light of compliance with the right-of-way rule.
What the law actually requires
The Highway Code is clear: in the absence of signs, you must give way to vehicles coming from the right. But it also specifies something else that is often forgotten: every driver must reduce their speed when approaching an intersection , even if they have priority.

Priority doesn’t mean “go for it.” It organizes the flow. Caution, however, always remains essential.
A simple reflex that changes everything
In suburban neighborhoods, small towns, and poorly signposted areas, these unmarked intersections are everywhere. Knowing them means driving more calmly and protecting everyone around you.
A glance to the right. A moment’s patience. And the road becomes smooth again for everyone.
