The traffic signals in St. John's are supposed to be vertical. When we first moved here we marveled at the way all the lights were held by cables and allowed to swing freely. After the first moderately* windy day where the lights flew horizontally of their own accord, much like flags, we then understood. Traffic lights as we had previously known them would've been snapped off.

* moderately on the St. John's scale is still pretty damn windy
