Chaos struck the 700 block of Commonwealth Avenue when a 24-year-old on a 150cc motorcycle collided with a MBTA Trolley, Boston’s transit police reported. The incident, which took place at around 6 p.m. yesterday, was caused as the unnamed young rider was looking at his phone, seemingly oblivious to the looming steel behemoth of public transport. In a breathtaking display of negligence, it was discovered that the operator was not only driving without a license but had also attached an unknown license plate to the motorcycle.
