In a study that surfaced Monday, Baton Rouge ranks as the second most dangerous city in the nation for drivers. Louisiana’s capital ranks behind only Detroit in a study of the 200 most populous cities done by NerdWallet, a financial education center. The group looked at five metrics: the rate of fatal crashes; the likelihood of a wreck relative to other cities; number of years between crashes; the risk of auto break-ins; and the risk of having a vehicle stolen. Those scores were then linked to annual auto insurance rates. The review said Baton Rouge had 38 fatal crashes in 2014, well under the 110 in Detroit.
