Read: Crash casts light on fan safety

The crash in Houston came almost two years after British driver Dan Wheldon died during a multi car wreck at the Las Vegas Indy 300.

Just months before his fatal crash in 2011, two-time Indianapolis 500 winner Wheldon had tested the prototype car chassis for the 2012 season.

Following his death, the chassis, designed by Italian company Dallara, was christened the DW-12 in his honor.

In May of last year, Dallara made further significant safety improvements to the chassis.

These steps to improve safety may have helped Franchitti avoid serious injury.

However, following the latest incident, IndyCar is once again reviewing safety for its drivers and fans.
