The question raised addresses a frequent doubt about the Portuguese Highway Code: when traveling at 120 km/h, which is the maximum permitted limit on highways, in the left lane, and a faster vehicle appears behind, is there any obligation to change to the right?
The article presents this question as one of the most common doubts among Portuguese drivers, suggesting that there is some confusion or lack of knowledge about the applicable rules in this situation.
However, the provided text ends abruptly in the phrase "This is a fairly common doubt..." without presenting the answer or explanation. The article appears to be incomplete, as it does not develop the content about what the applicable rule really is, nor does it offer the technical guidance on the correct behavior for the driver in this situation.
