If you are driving on a road marked with this sign, on the section between a merge and a diverge, why does the risk of collisions increase?
Signage: Vertical signs
On a weaving section, between a confluence and a divergence, many vehicles change lanes at the same time, causing their paths to cross. When these paths cross, the likelihood of conflicts increases and, therefore, so does the risk of collisions.
Explanation
Danger on a weaving section between a merge and a divergence
On a **weaving section** traffic is more dangerous because, between a **merge** (where vehicles join) and a **divergence** (where others exit), many vehicles carry out **lane changes** at the same time.
When **their paths cross** —some to enter, others to exit or change lane— the likelihood of **traffic conflicts** increases and, therefore, the **risk of collisions**.
