Why doesn’t the ministry install more median barriers? Wouldn’t this help prevent head on collisions?
Median barrier is effective in reducing head on collisions, however in most cases there is insufficient width to place barrier in a median area on an existing highway. The barrier itself is approximately 0.6m wide, plus an additional meter on each side of the barrier is required as a comfortable offset distance from the driving lane. In order to install median barrier, approximately 2.6m of width is required. On 2-lane highways, median barrier is not used except on isolated, very short highway segments prone to collisions—where adequate road width exists, or where the road can be widened.
