The high visibility vest makes sense because the most immediate danger is getting hit by some impatient distracted driver.
The SMG is a good upgrade over just his basic sidearm if a bit more firepower is needed, although inferior to an intermediate caliber carbine. It is probably open bolt so it would be difficult to fire single controlled accurate shots. Not ideal.
The helmet is definitely outdated, but sloped steel helmets like that can at least deflect bullets or offer some protection from blunt impact. If there is no major incident going on that old thing is probably uncomfortable and more trouble than it's worth.
