The 2019 Formula 1 season will welcome a series of new regulation tweaks, creating a revised look to the cars as part of a wider push to improve the sport.

New aerodynamic regulations have been introduced which aim to encourage closer racing and provide further opportunities for drivers to overtake.

The FIA hope that the introduction of simplified aerodynamic components will benefit races by reducing turbulent air currently left behind cars.

Pirelli have introduced a new coding system for its tyres in 2019 in a bid to make its compound choices easier to understand, with hard, medium and soft tyres being defined at each race by a lettering system ranging from C1 to C5.

Cars will also be allowed to carry 110kg of fuel onboard, representing a 5kg increase compared to last year.

Listed below are some of the other rule changes that may have missed the headlines, according to Autosport.

New racewear

The FIA have introduced new helmet requirements for 2019 following a sustained period of study and research to improve safety standards.

All helmets, which will be supplied by either Stilo, Bell, Racing, Schubert or Arai, must meet the new FIA standard.

The top visor opening has been lowered by 10mm to create advanced ballistic protection that achieves ‘unprecedented’ levels of safety in the case of a debris strike, while the helmet shell construction will use advanced composite materials to ensure it is tough enough to resist crushing and penetration.

Aid for heavy drivers

Driver weights will be classified separately from their car, rather than as a combined figure, which was 734kg in 2018.

In 2019, the weight of the driver and his seat will be measured at the start of the campaign and must be a minimum of 80kg.

Any driver under the limit will have a ballast fitted inside the cockpit area.

Grid Penalty alterations

The FIA have moved to send drivers to the back of the grid should they face more than a 15-place drop.

Those drivers starting at the back will be placed in the order they qualify – meaning even those relegated to the back will be forced to take part as much as possible on a Saturday afternoon.

Improved oil burn limitations

A new clause will be introduced from the start of the season stipulating that teams must keep their auxiliary oil tanks empty throughout qualifying.

This will prevent teams burning extra oil in the battle for pole position.

Safety car overtaking

Overtaking the first safety-car line is now not allowed until drivers have passed the start/finish line following a restart.

There will also be a change in flag procedure - green flags will now only begin at the start/finish line rather than being utilised around the track once the safety car has entered the pits.

Further experience for trainees

For 2019, an exemption to the 60-person team-personnel limit has been agreed, with fresh opportunities for inexperienced team members to get hands-on experience at a race track.

Teams will be able to have six individual exemptions throughout the year for trainee personnel to be used alongside their regular 60.

Teams responsible to scrutinise themselves

Rather than having regular checks by the FIA, teams must submit a declaration the day before the start of first practice – to reveal their cars comply fully with new regulations.

Teams that miss the deadline will not be allowed to compete.

Formation laps to start from pit-lane

Cars starting from the pitlane are now allowed to run at the back of the formation lap once the last car starting at the grid has passed the pit exit.

At the conclusion of the formation lap, said car must enter the pits again and take the start from the end of the pit-lane as before.

New chequered light signal at race end

A new chequered flag light signal will now be shown at the finish line once the full race distance has been completed.

The change in regulation has been installed due to last year’s Canadian Grand Prix chequered flag disaster, where model Winnie Harlow waived the flag a lap early.
