When driving through Brazil one of the recurring road features are quebra molas. Especially on the long interstate highways, a quebra mola marks the difference between a settlement that just happens to be alongside the road and a proper village.
Quebra mola
Villages and smaller cities relay on the quebra molas for traffic management. And indeed, wherever these wheel breaking road blocks are placed, a traffic light becomes unnecessary. The worst though are those that, at night, are without the yellow markers or the sign next to the road.
And while most Brazilian drivers have developed a sixth sense for these engine wrecking stoppages, I still find myself swearing frequently at the all but invisible blocks leading to a full braking…
Though apparently, it can even get worse.
