A dual carriageway continues as the A4032 into the centre of Bristol, with a speed limit. The M32 is a trunk road, therefore its maintenance and upkeep is paid for by Highways England, the national roads authority. Most of the road has two lanes in each direction, though an extended sliproad north of junction 2 provides a climbing lane, and the short section between junction 1 and the M4 has three lanes both ways.
M4 carbine minor stoppages and 11 major ones, followed by the FN SCAR with 226 stoppages and the HK416 with 233. Despite 863 minor stoppages—termed "class one" stoppages, which require 10 seconds or less to clear, or "class two" stoppages, which require more than ten seconds to clear—the M4 functioned well, with over 98 percent of the 60,000 total rounds firing without a problem.

Magazine failures caused 239 of the M4's 882 failures. Army officials said
